Mohammed dropped his pebbles and was left with 62*1/2=31 pebbles. He searched and found some of his lost pebbles, getting him back to 31+18=49 pebbles. He went home and removed beads, leaving him with 49-5=44 pebbles. #### 44
44
He also noticed that 12 of his remaining pebbles were noticeably heavier than the rest, likely a different type of stone.
The question asks how many pebbles Mohammed ended up with. Being a different type of stone that is heavier doesn't make them not pebbles — they are still pebbles, just heavier ones. A solver might be tempted to subtract 12 thinking 'different type of stone' means they aren't pebbles, but the text only says they were he...

Priya is trying to decide whether to do her business accounting herself or hire one bookkeeper. If she does it herself, she'll be able to do 6 fewer hours of contract work, losing $46/hour in missed income. The bookkeeper charges $109. How much more money will she have if she hires the bookkeeper?
Priya is trying to decide whether to do her business accounting herself or hire one bookkeeper. If she does it herself, she'll be able to do 6 fewer hours of contract work, losing $46/hour in missed income. The bookkeeper charges $109, though last year the same service would have cost her only $89. How much more money ...
First find the total lost revenue if Priya does her business accounting herself: $46/hour * 6 hours = $276 Then subtract the bookkeeper's charge to find how much money Priya saves: $276 - $109 = $167 #### 167
167
though last year the same service would have cost her only $89
The question asks how much more money she will have if she hires the bookkeeper NOW. The current bookkeeper rate is $109, which is what she would actually pay. What the service cost last year is irrelevant to the current decision. The calculation remains: (6 × $46) - $109 = $276 - $109 = $167.

The kernels increase to 5 times the initial popping rate in the next 14 seconds, but in the final 14 seconds, the popping s...
In the second k_3 seconds of cooking, 4* 40 = 160 kernels pop. In the third k_3 seconds, 5 * 40 = 200 kernels pop. In the final k_3 seconds, 200 / 2 = 100 kernels pop. After cooking, the residual heat makes 100 / 4 = 25 kernels pop. Thus, Thiago has 40 + 160 + 200 + 100 + 25 = 525 pieces of popcorn to eat. #### 525
525
Of all the kernels that popped, roughly 8% didn't fully expand and remained as partially popped half-kernels.
The question asks how many pieces of popcorn Thiago has to eat. Partially popped kernels are still popped kernels — they still count as pieces of popcorn. The clause tempts the solver to subtract 8% of the total, but whether a kernel fully expanded or only partially popped doesn't change the count of popped kernels. Th...

Andre works a 12-hour shift each day, 6 days a week. He earns €13 per hour and gets a €132 bonus each week if the company performs well. How much money did Andre make in October if the company performed very well for the whole month?
Andre works a 12-hour shift each day, 6 days a week. He earns €13 per hour, having received a raise from €11 per hour back in September. He also gets a €132 bonus each week if the company performs well. How much money did Andre make in October if the company performed very well for the whole month?
In a day, Andre makes 12 * 13 = €156 If he works 6 days a week, the total number of days for the whole month is 6 * 4= 24 days. Since he makes €156 per day, the total amount for the whole month is 24 * 156= €3744. He also got a 132 * 4 = €528 bonus because the company performed well in all the weeks of October. At the ...

having received a raise from €11 per hour back in September
The raise happened in September, so throughout all of October Andre's rate is €13 per hour. The previous rate of €11 is irrelevant since the question asks about October earnings only. However, it tempts solvers to somehow blend or average the two rates, or to second-guess which rate applies.

To make a call from a phone booth, you must pay ₣0.6 for each minute of your call. After 30 minutes, that price drops to ₣0.5 per minute. How much would a 78-minute call cost?
To make a call from a phone booth, you must pay ₣0.6 for each minute of your call. After 30 minutes, that price drops to ₣0.5 per minute. If you had placed the same call on a weekend, the initial per-minute rate would have been 15% cheaper. How much would a 78-minute call cost on a weekday?
First 30 minutes would be a cost of 30 * 0.6 = ₣18. After that, there are 78 - 30 = 48 minutes of the call left. And these 48 minutes cost 48 * 0.5 = ₣24. So in total, the 78-minute call would cost 18 + 24 = ₣42. #### 42
42
If you had placed the same call on a weekend, the initial per-minute rate would have been 15% cheaper.
The question explicitly asks about the cost of a weekday call. The weekend discount is a hypothetical alternative scenario that does not apply. The calculation remains: 30 × ₣0.6 + 48 × ₣0.5 = ₣18 + ₣24 = ₣42.

He takes 8+2=10 classes a day That means he spends 45*10=450 minutes per day in class So he spends 450*6=2700 minutes a week That means he spends 2700*1/6=450 minutes each on Saturday and Sunday. So he spends 2700+450+450=3600 minutes per week So he spends 3600/60=60 hours per week #### 60

However, on Sundays, he covers the material twice as fast since he is reviewing what he already studied on Saturday.
The question asks how many hours he spends learning, which is a measure of TIME spent, not the amount of material covered. Covering material faster doesn't change the fact that he still spends one-sixth of his weekly minutes on Sunday as extra learning time. The time spent is explicitly defined; his efficiency or speed...

Esteban went to their allotment to pick some raspberries and found nine times as many wasps as grasshoppers in the patch. If there were 185 grasshoppers, calculate the total number of insects in the patch.
Esteban went to their allotment to pick some raspberries and found nine times as many wasps as grasshoppers in the patch. If there were 185 grasshoppers, but 12 of the grasshoppers hopped away before Esteban finished counting, calculate the total number of insects in the patch.
If there were 185 grasshoppers, the total number of wasps in the patch is 9 * 185 grasshoppers = 1665 wasps The total number of insects in the patch is 1665 wasps + 185 grasshoppers = 1850 insects #### 1850

but 12 of the grasshoppers hopped away before Esteban finished counting
The question states there WERE 185 grasshoppers in the patch and asks for the total number of insects in the patch. The fact that some hopped away before Esteban finished counting doesn't change how many were actually there — 185 is presented as the established count. The ratio (9×) was also based on what was in the pa...

Kai hires a luxury car from 1 PM to 5 PM. He gets 2 hours free. The first paid hour is $10 and each hour after that is twice the cost. How much did he pay?
Kai hires a luxury car from 1 PM to 5 PM. He gets 2 hours free. The first paid hour is $10 and each hour after that is twice the cost. How much did he pay, given that the rental company charges a 15% surcharge for bookings after 6 PM?
He got it for 5-1=4 hours He pays for 4-2=2 hours The first hour cost 1*10=$10 The other 2-1=1 hours are more expensive They cost 10*2=$20 per hour So those 1 hours cost 1*20=$20 So he pays 20+10=$30 #### 30
30
given that the rental company charges a 15% surcharge for bookings after 6 PM
Kai's rental is from 1 PM to 5 PM, which ends before 6 PM. The surcharge for bookings after 6 PM does not apply to his rental period, so the answer remains unchanged: 4 hours total - 2 free = 2 paid hours. First paid hour = $10, second paid hour = $20. Total = $30.

In the second k_3 seconds of cooking, 2* 40 = 80 kernels pop. In the third k_3 seconds, 3 * 40 = 120 kernels pop. In the final k_3 seconds, 120 / 2 = 60 kernels pop. After cooking, the residual heat makes 60 / 4 = 15 kernels pop. Thus, Viktor has 40 + 80 + 120 + 60 + 15 = 315 pieces of popcorn to eat. #### 315
315
Of all the kernels Viktor started with, 8% never popped at all and remained as unpopped kernels at the bottom of the skillet.
The question asks how many pieces of POPCORN Viktor has to eat — meaning the kernels that successfully popped. The problem already tracks exactly how many kernels pop during each time interval and from residual heat, giving us the total popped count directly (315). The unpopped kernels are a separate group that never b...

The tower of stacking rings has 30 multicolored rings on it. Emma recently bought a tube of bouncy balls, bringing her total number of toys for ...
Let T be the number of bouncy balls in the tube. After buying the tube of balls, Emma has 74 + 37 + 30 + T = 141 + T = 215 toys for her cousin. Thus, T = 215 - 141 = 74 bouncy balls came in the tube. #### 74

However, she noticed that 12 of the building blocks were duplicates of ones she already had in a separate collection at home.
The duplicates are of blocks in a separate collection at home — the bag still contains 74 blocks that she gets out for her cousin. The question is about the total number of toys she has for her cousin (215), and all 74 blocks are part of that total regardless of whether some happen to match blocks in another collection...

The area of Gabriel's rectangular living room is 1005 square feet. If the length of his room is 5 yards, what is the perimeter of the room in feet?
The area of Gabriel's rectangular living room is 1005 square feet. If the length of his room is 5 yards, and Gabriel recently removed a 3-foot-wide strip of old carpet along one wall to expose the hardwood floor underneath, what is the perimeter of the room in feet?
The length of the room is 5 yards * (3 feet / 1 yards) = 15 feet. The width of the room is 1005 square feet / 15 feet = 67 feet. The room's perimeter is 2(67+15) = 164 #### 164

and Gabriel recently removed a 3-foot-wide strip of old carpet along one wall to expose the hardwood floor underneath
Removing carpet from part of the floor does not change the dimensions of the room. The perimeter is determined by the room's length and width, which remain unchanged. The 3-foot-wide strip might tempt the solver to subtract 3 feet from the width (67 feet) or otherwise adjust a dimension, but the room's actual measureme...

A fog bank rolls in from the ocean to cover a city. It takes 375 minutes to cover every 15 miles of the city. If the city is 15 miles across from the oceanfront to the opposite inland edge, how many minutes will it take for the fog bank to cover the whole city?
A fog bank rolls in from the ocean to cover a city. It takes 375 minutes to cover every 15 miles of the city. If the city is 15 miles across from the oceanfront to the opposite inland edge, and the fog bank has already dissipated over 5 miles of ocean before reaching the city, how many minutes will it take for the fog ...
The city will be covered in 15/ 15 = 1 intervals of 375 minutes. Thus, it will take 1 * 375 = 375 minutes for the fog to cover the whole city. #### 375

and the fog bank has already dissipated over 5 miles of ocean before reaching the city
The question asks how long it takes the fog to cover the city, which is 15 miles across. The fog's rate is given as 375 minutes per 15 miles. What happened over the ocean before the fog reached the city is irrelevant — the coverage of the city itself is still 15 miles at the stated rate. A solver might be tempted to su...

To make a call from a hotel room phone, you must pay ₣0.8 for each minute of your call. After 15 minutes, that price drops to ₣0.4 per minute. How much would a 45-minute call cost?
To make a call from a hotel room phone, you must pay ₣0.8 for each minute of your call. After 15 minutes, that price drops to ₣0.4 per minute. How much would a 45-minute call cost if the hotel also offers a ₣5 flat-rate connection fee for calls made from the lobby, which you are not using?
First 15 minutes would be a cost of 15 * 0.8 = ₣12. After that, there are 45 - 15 = 30 minutes of the call left. And these 30 minutes cost 30 * 0.4 = ₣12. So in total, the 45-minute call would cost 12 + 12 = ₣24. #### 24
24
if the hotel also offers a ₣5 flat-rate connection fee for calls made from the lobby, which you are not using
The ₣5 connection fee applies only to calls made from the lobby. The question specifies the call is made from a hotel room phone, so the lobby fee does not apply. The answer remains (15 × ₣0.8) + (30 × ₣0.4) = ₣12 + ₣12 = ₣24.

Santiago slew 1/2 as many ogres as Ali, or 150*1/2=75 ogres. DeShawn slew 8 as many ogres as Santiago, or 8*75=600 ogres. Tariq slew 1/2 as many ogres as DeShawn, or 600*1/2=300 ogres. #### 300

though 15 of the ogres he faced were juveniles half the size of normal ogres
The question asks how many ogres Tariq slew — a count of ogres killed. The size of some ogres being smaller doesn't change the number of ogres slain. A solver might be tempted to count juveniles as half an ogre each (subtracting 7.5 or similar), but slaying an ogre is slaying an ogre regardless of its size.

A full outfit for each child will require 15 skeins per tunic + 7 skeins per shawl + 6 skeins per sweater + 5 skeins per pair of socks + 13 skeins per pair of mittens = 46 skeins of wool. So to knit outfits for all of her grandchildren, she will need 3*46 = 138 skeins of wool. #### 138

She already has 4 skeins of wool left over from a previous project, but they're a different color so she won't use them for this.
The clause introduces existing skeins that might tempt the solver to subtract 4 from the total, but it explicitly states she won't use them for this project because they're a different color. Since she can't use them, they don't reduce the amount she needs to buy. The answer remains (15 + 7 + 6 + 5 + 13) × 3 = 46 × 3 =...

It takes Gabrielle 6 minutes to finish a riddle and 3 minutes to finish a brain teaser. Over the free time she solved 9 riddles and 5 brain teasers, though 2 of the brain teasers were ones she had already solved once before in a previous session. How much time did she spend playing these games?
It takes 6 minutes to complete a riddle and she completed 9 for a total of 6*9 = 54 minutes It takes 3 minutes to complete a brain teaser and she completed 5 for a total of 3*5 = 15 minutes She spent 54 minutes on riddles and 15 minutes on brain teasers for a total of 54+15 = 69 minutes #### 69

though 2 of the brain teasers were ones she had already solved once before in a previous session
The question asks how much time she spent playing these games during this session. Whether she had solved some of them before doesn't change the fact that she still solved 5 brain teasers now, each taking 3 minutes. Having prior experience might tempt a solver to subtract those 2 brain teasers or reduce their time, but...

While Sakura is processing 55 orders in a day, Nia processes 55 orders/day * 3 = 165 orders/day. In a day, they process 165 orders/day + 55 orders/day = 220 orders together. The total number of orders the two processes in a week is 220 orders/day * 7 days/week = 1540 orders #### 1540

considering that on weekends each customer transaction takes about 20% longer due to larger purchases
The question states how many customers each person processes daily (Sakura: 55, Nia: 165) and asks for total weekly production. The number of customers processed per day is already given as a fixed daily rate. Transactions taking longer per customer on weekends sounds like it should reduce throughput, but the problem d...

Nadia receives 100 emails a day. 16% of those emails don't require any response. Nadia responds to the rest of them. How many emails does Nadia respond to in a 4 day work week?
Nadia receives 100 emails a day. 16% of those emails don't require any response. Nadia responds to the rest of them. How many emails does Nadia respond to in a 4 day work week, given that she had already responded to 45 emails from the previous week before this work week started?
Nadia receives 16.0=16 emails that don't require a response So Nadia responds to 100-16=84 emails per day In a 4 day work week, Nadia responds to 84*4= 336 emails #### 336
336
given that she had already responded to 45 emails from the previous week before this work week started
The question asks how many emails Nadia responds to IN a 4 day work week. Emails she responded to from a previous week are not part of this work week's count. The 84 emails per day × 4 days = 336 remains unchanged. However, a model might be tempted to add or subtract the 45 previous-week emails from the total.

Mia's flower bed is 195 meters / 15.0 meters per plant = 13 plants needed. Mia needs to buy 13 plants - 12 plants = 1 plants needed to purchase. Mia will spend 1 plants * €14 = €14. #### 14
14
though last month they were on sale for €12 each
The question asks how much Mia will spend at the store now. The current price is €14 per plant. What the plants cost last month during a sale is irrelevant to what she pays today. This mirrors the inflation example from the paper — past prices don't affect current spending. The answer remains 1 plant × €14 = €14.

Thiago has 60 hectares of pear field. There are 69 pears per hectare. Thiago can harvest his pears every 2 months, although he typically lets 5 hectares rest each cycle by rotating which ones are resting. How many pears can Thiago harvest within a year?
Thiago has 69 x 60= 4140 pears on his field. Thiago can harvest his pears 12 ÷ 2 = 6 times per year Therefore Thiago can harvest 4140 x 6 = 24840 pears per year. #### 24840

The clause says Thiago rotates WHICH 5 hectares rest each cycle. Since he harvests 6 times a year (every 2 months) and rotates the resting hectares, every hectare still gets harvested in the cycles it isn't resting. But more importantly, the question asks how many pears he CAN harvest within a year — the field yields 6...

The Smith family is busy making muffins. So far, they've made 9550 muffins. They have 2165 peanut butter muffins, 1869 strawberry muffins, and some blueberry muffins. They plan to set aside 350 of the blueberry muffins to give to their neighbors later today. How many blueberry muffins have they made?
The total number of pieces of peanut butter and strawberry muffins is 2165 + 1869 = 4034. Therefore, they made 9550 - 4034 = 5516 blueberry muffins. #### 5516

They plan to set aside 350 of the blueberry muffins to give to their neighbors later today.
The question asks how many blueberry muffins they have MADE, not how many they will keep. Setting aside some to give away doesn't change the total number produced.

even though muffins at the bakery next door are 25% cheaper
The question asks how much everything cost at the store where Oscar actually bought the items. The price of muffins at a different bakery he didn't visit is irrelevant — he paid ₺4 for the muffin at this store. The cheaper alternative doesn't change what he actually spent. The answer remains 7 × ₺13 + ₺4 = ₺95.

Jin places crackers on some trays. Each tray can hold 24 crackers. If he has 316 crackers and 8 trays, how many crackers won't he be able to place on the tray?
Jin places crackers on some trays. Each tray can hold 24 crackers. If he has 316 crackers and 8 trays, but 2 of the trays already have 12 crackers each from a previous batch that are included in his total of 316 crackers, how many crackers won't he be able to place on the tray?
Jin will be able to place a total of 24 x 8 = 192 crackers. Therefore, there are 316 - 192 = 124 crackers that he won't be able to place on the tray. #### 124

but 2 of the trays already have 12 crackers each from a previous batch that are included in his total of 316 crackers
Since the 24 crackers already on the 2 trays are included in the total of 316, the capacity calculation doesn't change. The 8 trays still hold 8 × 24 = 192 crackers total, and 316 - 192 = 124 crackers still won't fit. The clause tempts solvers to think some tray capacity is already used up or to subtract/add those 24 c...

Nadia and Santiago are currently 12 years apart in age. If Nadia, who is younger than Santiago, is 62 years old, and 5 years ago the sum of their ages was used to calculate a family membership discount, what's the average of their ages?
If Nadia is 62 years old, Santiago is 62+12 = 74 years old. The sum of their ages is 74+62 = 136 years The average age of the two is 136/2 = 68 years #### 68

If Jamal and Oliver have 420 feet of fence between them, and they agree to split it with Oliver getting 180 feet more than Jamal, how much is left over for Jamal?
If Jamal and Oliver have 420 feet of fence between them, and they agree to split it with Oliver getting 180 feet more than Jamal, but Jamal already used 40 feet of his own personal fencing on a garden project last weekend, how much is left over for Jamal?
Let x be the amount of fence Jamal gets and y be the amount Oliver gets. We know that y = x + 180, and y + x = 420. Substituting the first equation into the second equation, we get 2x+180=420 Subtracting the 180 from both sides, we get 2x=240 We divide each side by two, leaving x=120. This means Jamal has 120 feet of f...

but Jamal already used 40 feet of his own personal fencing on a garden project last weekend
The question asks how much of the shared 420 feet Jamal receives from the split. The 40 feet Jamal used last weekend was from his own personal fencing, not from this 420-foot pool they are splitting now. The split still gives Jamal (420 - 180) / 2 = 120 feet. However, a solver might be tempted to subtract 40 from Jamal...

The Scavenger hunt team hid 200 toys. The Johnson twins each found 35 toys. All the other toys except 15 were found by their friends. How many toys did the friends find?
The Scavenger hunt team hid 200 toys. The Johnson twins each found 35 toys, but 10 of those toys were duplicates that both twins had spotted at the same time before dividing them between themselves. All the other toys except 15 were found by their friends. How many toys did the friends find?
The Johnson twins found, 35 * 2 = 70 toys. The number that remained hidden was 200 - 70 = 130 toys Since 15 toys were not found, this means the friends found 130 - 15 = 115 toys. #### 115

The statement says each twin found 35 toys, so together they found 70 toys total. The fact that 10 of those toys were spotted by both twins before being divided between them doesn't change the count — each twin still ended up with 35 toys, totaling 70.

The total ratio representing the ingredients she used to make the tea is 135+21 = 156 Since the fraction representing the number of teaspoons she used is 135/156, she used 135/156*468 = 405 #### 405

keeping in mind that for every cup of water she actually dissolved only 3/4 of a teaspoon of sugar completely while the rest settled at the bottom
The question asks how many teaspoonfuls of sugar she USED, not how many dissolved. Whether the sugar dissolved or settled at the bottom, she still used the same total amount. The ratio 135:21 and total of 468 determine that she used 405 teaspoons of sugar regardless of how much dissolved.

Luca has 40 square meters of banana field. There are 72 bananas per square meter. Luca can harvest his bananas every 12 months, though he recently expanded his field by 10 square meters that won't produce any bananas until next year. How many bananas can Luca harvest within a year?
Luca has 72 x 40= 2880 bananas on his field. Luca can harvest his bananas 12 ÷ 12 = 1 times per year Therefore Luca can harvest 2880 x 1 = 2880 bananas per year. #### 2880

If Keisha can skip at 3/4 the speed she can run, then she can run at 3*4/3=4 miles per hour. And since she can run at a speed that is 8 times faster than she can walk, this means she can walk at 4/8=1/2 miles per hour. If 1/2 of the time is spent walking, then she walks for 8*1/2=4 hours.

Winnie is only buying 22 nuts, which is fewer than the 25 needed to qualify for the bulk discount. The discount threshold is never met, so the price remains ¥0.65 per nut. The answer is still 82.3 - (22 × 0.65) = 82.3 - 14.3 = 68.

though they could have saved 8 minutes by cutting through the mall instead of going around it
The question asks how much time they have LEFT to reach the park given the time already spent. They actually took 19 + 64 = 83 minutes, so they have 96 - 83 = 13 minutes remaining. The fact that they COULD HAVE saved 8 minutes by taking a shortcut doesn't change how long they actually took. The hypothetical alternative...

Wei is 10 years old. In 7 years his cousin Chen will be 3 times as old as Wei is now. How old is Chen right now?
Wei is 10 years old. In 7 years his cousin Chen will be 3 times as old as Wei is now. Wei's younger brother is exactly half Wei's current age. How old is Chen right now?
7 years from now Chen will be 10*3=30. Right now Chen is 30-7=23 years old. #### 23

Wei's younger brother is exactly half Wei's current age.
The younger brother's age is completely unrelated to the calculation of Chen's age. The problem only requires knowing Wei's current age (10) and the relationship that in 7 years Chen will be 3×10 = 30, so Chen is currently 30 - 7 = 23. However, the mention of a younger brother who is 'half Wei's age' (i.e., 5) tempts t...

Diego works a 10-hour shift each day, 3 days a week. He earns €14 per hour and gets a €390 bonus each week if the company performs well. How much money did Diego make in July if the company performed very well for the whole month?
Diego works a 10-hour shift each day, 3 days a week. He earns €14 per hour, which is €2 more than what he earned per hour in June before his raise. He also gets a €390 bonus each week if the company performs well. How much money did Diego make in July if the company performed very well for the whole month?
In a day, Diego makes 10 * 14 = €140 If he works 3 days a week, the total number of days for the whole month is 3 * 4= 12 days. Since he makes €140 per day, the total amount for the whole month is 12 * 140= €1680. He also got a 390 * 4 = €1560 bonus because the company performed well in all the weeks of July. At the en...

Mateo caught 7 cods last Thursday, the first cod he caught weighs 77 pounds, the second cod he caught weighs 51 pounds, and the last cod he caught weighs 20 pounds. If a pound of cod costs ¥0.5, how much will he earn after selling all the cods to the market?
Mateo caught 7 cods last Thursday, the first cod he caught weighs 77 pounds, the second cod he caught weighs 51 pounds, and the last cod he caught weighs 20 pounds. The remaining 4 cods each weigh the same as the last cod. If a pound of cod costs ¥0.5, but the market was offering a 15% premium on purchases over 200 pou...
Mateo will earn 77 x ¥0.5 = ¥38.5 from the first cod. He will earn 51 x ¥0.5 = ¥25.5 for the second cod. The rest of the cods are 7-2 = 5. He will earn 20 x ¥0.5 = ¥10.0 per each of them. So he will earn 5 * 10.0 = =50.0 Therefore, the total amount he will earn for all the cods is ¥38.5 + ¥25.5 + ¥50.0= ¥114. #### 114

On the beach, Leilani walks at a rate of 14 miles per 56 minutes, or 14/56 = 1/4 miles per minute. On the sidewalk, she walks at 2 times the rate of speed as when she is on the sand, or 2 * 1/4 = 1/2 miles per minute. To walk 11 miles on the sidewalk, it takes her 11÷1/2=22 minutes.

There are 82 third-graders at Oak Ridge School. 62 of them are girls. On Wednesday, 3 third-grade girls and 8 third-grade boys were absent. How many third grade boys were at Oak Ridge School on Wednesday?
There are 82 third-graders at Oak Ridge School. 62 of them are girls. On Wednesday, 3 third-grade girls and 8 third-grade boys were absent. Additionally, 5 second-graders joined the third-grade classroom temporarily for a reading activity that morning. How many third grade boys were at Oak Ridge School on Wednesday?
Of the 82 third graders, 62 are girls, so 82 students - 62 girls = 20 boys. On Wednesday there were 20 boys - 8 absent = 12 boys. #### 12

Additionally, 5 second-graders joined the third-grade classroom temporarily for a reading activity that morning.
The question asks how many third-grade boys were at school on Wednesday. The second-graders who joined the classroom are not third-graders, so they don't count toward the number of third-grade boys present. The answer remains: 82 - 62 = 20 boys total, 20 - 8 absent = 12 third-grade boys present.

She had a coupon for ₺4 off the package ...
The leggings were ₺12 more than the jersey, so they cost ₺12 + ₺16 = ₺28. Her cleats were 3/4 the original ₺76 price, so they cost ₺76 * 3/4 = ₺57. With her coupon, the headbands were ₺11 - ₺4 = ₺7. The jersey, leggings, cleats, and headbands together cost ₺16 + ₺28 + ₺57 + ₺7 = ₺108. #### 108

Her teammate also went shopping the same day and spent 20% more than Leilani did.
The question asks how much Leilani spent, not her teammate. The teammate's spending is defined relative to Leilani's total but is never asked about. However, the mention of '20% more' tempts the solver to compute an additional amount or mistakenly adjust Leilani's total.

At the beginning of the conference, there were 52 engineers and 63 nurses. After 45 minutes, four-fifths of the total number of people left. During the conference, 8 of the engineers had also been certified as nurses earlier in their careers. How many nurses are left if 21 engineers stayed at the conference?
There were a total of 52 engineers + 63 nurses = 115 people who attended the conference. After 45 minutes, 115 people * 4/5 = 92 people left the conference. This means 115 people - 92 people = 23 people stayed. Out of the 23 who stayed, 23 people - 21 engineers = 2 were nurses. #### 2

There are 11 students playing basketball and seven times that number playing badminton. There are 15 boys and 10 girls playing football, but 5 of the football players also signed up as substitutes for basketball before being told each student can only participate in one group. If each student only participates in one g...
There are 11 x 7 = 77 students playing badminton. There are 15 + 10 = 25 students playing football. In total there are 11 + 77 + 25 = 113 students. #### 113

but 5 of the football players also signed up as substitutes for basketball before being told each student can only participate in one group
The clause says 5 football players initially signed up for basketball too, but they were told each student can only participate in one group — which is the constraint already stated. So they ended up in only one group (football). The final counts remain unchanged: 11 basketball + 77 badminton + 25 football = 113. The t...

Prof. Brown sold his villa for $580000. He paid the registration fees that amount to 2% of the selling price and also paid a agent fee that is 4% of the selling price. If he also paid $170000 for the remaining loan amount of the villa, how much is Prof. Brown's net proceeds from selling the villa?
Prof. Brown sold his villa for $580000. He had originally purchased the villa for $320000 fifteen years ago. He paid the registration fees that amount to 2% of the selling price and also paid a agent fee that is 4% of the selling price. If he also paid $170000 for the remaining loan amount of the villa, how much is Pro...
Prof. Brown paid $580000 x 2/100 = $11600 for the registration fees. He paid $580000 x 4/100 = $23200 for the agent fee. So, Prof. Brown paid a total of $11600 + $23200 + $170000 = $204800 for the registration, agent, and loan fees. Hence, Prof. Brown's net proceeds is $580000 - $204800 = $375200. #### 375200

He had originally purchased the villa for $320000 fifteen years ago.
The question asks for net proceeds from the sale, which is the selling price minus fees and loan payoff. The original purchase price is irrelevant to computing net proceeds — it would only matter if the question asked about profit or capital gains. A model might be tempted to subtract the purchase price or factor it in...

Arash went to buy some school supplies. He bought 18 colored pencils which cost ¥5.5 each, 8 pencils which cost ¥16.25 each, and a rim of bond paper which cost ¥24. How much did Arash spend on everything?
Arash went to buy some school supplies. He bought 18 colored pencils which cost ¥5.5 each, 8 pencils which cost ¥16.25 each, and a rim of bond paper which cost ¥24. How much did Arash spend on everything, given that the store was offering a 15% discount on items over ¥50 but none of Arash's individual items exceeded th...
Arash spent 18 x ¥5.5 = ¥99 for the colored pencils. He also spent 8 x ¥16.25 = ¥130 for the pencils. Therefore, Arash spent a total of ¥99 + ¥130 + ¥24 = ¥253 for the school supplies. #### 253
253
given that the store was offering a 15% discount on items over ¥50 but none of Arash's individual items exceeded that price
The discount applies only to individual items priced over ¥50. Since no single item Arash bought costs more than ¥50 (colored pencils are ¥5.5 each, pencils are ¥16.25 each, bond paper is ¥24), the discount never triggers. The total remains ¥253. However, a solver might be tempted to apply the 15% discount to the total...

The area of Alejandro's rectangular living room is 651 square feet. If the length of his room is 7 yards, what is the perimeter of the room in feet?
The area of Alejandro's rectangular living room is 651 square feet. If the length of his room is 7 yards, and Alejandro recently extended the room's ceiling height from 8 feet to 10 feet during a renovation, what is the perimeter of the room in feet?
The length of the room is 7 yards * (3 feet / 1 yards) = 21 feet. The width of the room is 651 square feet / 21 feet = 31 feet. The room's perimeter is 2(31+21) = 104 #### 104

Perimeter is a 2D measurement of the floor's boundary. Ceiling height affects volume but has no impact on the perimeter calculation. However, the mention of a dimensional change in feet tempts the solver to incorporate it into their computation, especially since the problem already involves unit conversion between yard...

A carton of sparkling water is 9 ounces of sparkling water. Thiago drinks 5 cartons of sparkling water, though he only finished 3 of them in one sitting and saved the rest for later. If sparkling water has 2 calories per ounce how many calories did he consume?
He drank 9*5=45 ounces of sparkling water. So he drank 45*2=90 calories of sparkling water #### 90

though he only finished 3 of them in one sitting and saved the rest for later
The question states he drinks 5 cartons total. Whether he drank them all at once or split them across sittings doesn't change the total amount consumed — he still drank all 5 cartons. The clause tempts the solver to only count 3 cartons, but 'saved the rest for later' implies he still drank them, just at a different ti...

Aisha has written the alphabets 7 time(s) which is a total of 48 * 7 = 336 letters. She then writes 2/3 the 48, which is 48 * 2/3 = 32 letters. So far, this is a total of 336 + 32 = 368 letters.

During her first pass, she noticed that 15 of the letters she wrote were incorrect and would need to be corrected later.
The question asks how many letters Aisha has written in total, not how many she wrote correctly. Incorrect letters are still letters she wrote and are counted in 'everything she has already written' when she re-writes it all. The correction would happen 'later' — outside the scope of the described actions. The total wr...

Chen went to the cafe and bought various types of treats. She bought 3 dozen danishes which cost $12 per dozen, 8 dozen tarts which cost $82 per dozen, and 6 dozen scones for $113 per dozen. The cafe was running a loyalty program where every 5th visit earns a 15% discount, but this was only Chen's 3rd visit. How much w...
The total charge for the danishes was 3 x $12 = $36. The total charge for the tarts was 8 x $82 = $656. The total charge for the scones was 6 x $113 = $678. Therefore the total amount Chen paid for the treats was $36 + $656 + $678 = $1370. #### 1370

The cafe was running a loyalty program where every 5th visit earns a 15% discount, but this was only Chen's 3rd visit.
The 15% discount only applies on the 5th visit, and Chen is only on her 3rd visit, so no discount is applied. The total cost remains 3×12 + 8×82 + 6×113 = 36 + 656 + 678 = 1370. However, the mention of a specific percentage discount tempts the solver to apply 15% off the total.

The Johnson family is busy making biscuits. So far, they've made 9925 biscuits. They have 1670 peanut butter biscuits, 1218 lemon biscuits, and some blueberry biscuits. They plan to give away 350 of the blueberry biscuits to their neighbors later today. How many blueberry biscuits have they made?
The total number of pieces of peanut butter and lemon biscuits is 1670 + 1218 = 2888. Therefore, they made 9925 - 2888 = 7037 blueberry biscuits. #### 7037

They plan to give away 350 of the blueberry biscuits to their neighbors later today.
The question asks how many blueberry biscuits they have MADE, not how many they will have after giving some away. The total made is determined by subtracting the peanut butter and lemon counts from the total biscuits made. Future plans to give some away don't change how many were made. The answer remains 9925 - 1670 - ...

When Aisha watches her brother, she gets out a variety of toys for him. The bag of building blocks has 72 blocks in it. The bin of stuffed animals has 36 stuffed animals inside. The tower of stacking rings has 22 multicolored rings on it. Aisha recently bought a tube of bouncy balls, bringing her total number of toys f...
Let T be the number of bouncy balls in the tube. After buying the tube of balls, Aisha has 72 + 36 + 22 + T = 130 + T = 153 toys for her brother. Thus, T = 153 - 130 = 23 bouncy balls came in the tube. #### 23

However, 15 of the building blocks were duplicates of ones she already had before the bag was packed.
The question states the bag has 72 blocks in it — that's the count of blocks in the bag regardless of whether some are duplicates of previously owned blocks. Duplicates are still blocks and still count toward the total number of toys. The total is 153 toys, so bouncy balls = 153 - 72 - 36 - 22 = 23. A solver might be t...

Faisal caught 4 cods last Friday, the first cod he caught weighs 47 kgs, the second cod he caught weighs 55 kgs, and the last cod he caught weighs 24 kgs. If a kg of cod costs ¥1.0 and Faisal had to throw back one undersized fish earlier in the day before catching these four, how much will he earn after selling all the...
Faisal will earn 47 x ¥1.0 = ¥47.0 from the first cod. He will earn 55 x ¥1.0 = ¥55.0 for the second cod. The rest of the cods are 4-2 = 2. He will earn 24 x ¥1.0 = ¥24.0 per each of them. So he will earn 2 * 24.0 = =48.0 Therefore, the total amount he will earn for all the cods is ¥47.0 + ¥55.0 + ¥48.0= ¥150. #### 150

and Faisal had to throw back one undersized fish earlier in the day before catching these four
The fish that was thrown back is not one of the 4 cods he caught and kept. He sells the 4 cods he actually caught, so the thrown-back fish doesn't affect his earnings. The temptation is to think he only has 3 cods to sell instead of 4. The answer remains (47 + 55 + 24 + 24) × ¥1.0 = ¥150.

However, titanium pickaxes require maintenance every 10 days, during which the trolls sharpen them using 2 kgs of ore from their personal reserve rather than from the daily mining output.
The ore used for maintenance comes from the trolls' personal reserve, not from the daily mining output. The question asks how many kgs of ore the trolls can mine, and the maintenance ore is drawn from a separate source, so the total mined ore remains unchanged at 20 trolls × 16 kg/day × 30 days = 9600 kgs.

Comet Hale-Bopp orbits the sun every 55 years. Yusuf's father saw the Comet when he was 24 years old. Yusuf saw the comet a second time when he was three times the age his father was when he saw the Comet. How old was Yusuf when he saw the Comet for the first time?
Comet Hale-Bopp orbits the sun every 55 years. Yusuf's father saw the Comet when he was 24 years old. Yusuf's father was 32 years older than Yusuf. Yusuf saw the comet a second time when he was three times the age his father was when he saw the Comet. How old was Yusuf when he saw the Comet for the first time?
Yusuf saw the Comet for the second time when he was 24 years * 3= 72 years old. Comet Hale-Bopp can be seen every 55 years, so Yusuf saw the comet for the first time when he was 72 years - 55 years = 17 years old. #### 17

Yusuf's father was 32 years older than Yusuf.
The age gap between Yusuf and his father is irrelevant because the problem only needs: (1) the comet's orbital period (55 years), (2) the father's age when he saw it (24), and (3) Yusuf's age when he saw it the second time (3 × 24 = 72). Yusuf's first sighting was one orbit earlier: 72 − 55 = 17. The father-son age dif...

However, each room can technically hold up to 2 patients if needed, though current policy assigns one patient per room. Calculate the total number of unoccupied rooms in the car...
If 2/5 of the total capacity of the care facility rooms is occupied, it means 2/5 * 1900 = 760 rooms have patients using them.

considering that on average 15% of the customers Olivia processes end up not making a purchase
The question asks about the total number of customers PROCESSED (i.e., handled at the cash register), not the number of customers who complete a purchase. Whether or not a customer ultimately makes a purchase doesn't change the fact that Olivia processed them at the register. The production metric is customers processe...

A cup of tea is 10 ccs of tea. Noah drinks 4 cups of tea. If tea has 2 calories per cc how many calories did he consume?
A cup of tea is 10 ccs of tea. Noah drinks 4 cups of tea, though he added 2 ccs of zero-calorie sweetener to each cup. If tea has 2 calories per cc how many calories did he consume?
He drank 10*4=40 ccs of tea. So he drank 40*2=80 calories of tea #### 80
80
though he added 2 ccs of zero-calorie sweetener to each cup
The sweetener has zero calories, so even though it adds volume to each cup (tempting the solver to compute calories on 12 ccs per cup), it contributes no calories. The caloric content comes only from the 10 ccs of tea per cup, so the answer remains 4 × 10 × 2 = 80.

Jamal went to buy some school supplies. He bought 24 notebooks which cost $8.5 each, 10 markers which cost $12.0 each, and a rim of bond paper which cost $22. How much did Jamal spend on everything?
Jamal went to buy some school supplies. He bought 24 notebooks which cost $8.5 each, 10 markers which cost $12.0 each, and a rim of bond paper which cost $22. If Jamal had waited until next week, the store would have offered a 15% discount on all items. How much did Jamal spend on everything?
Jamal spent 24 x $8.5 = $204 for the notebooks. He also spent 10 x $12.0 = $120 for the markers. Therefore, Jamal spent a total of $204 + $120 + $22 = $346 for the school supplies. #### 346
346
If Jamal had waited until next week, the store would have offered a 15% discount on all items.
The question asks how much Jamal DID spend, not how much he WOULD have spent. He already made the purchase at the stated prices. The hypothetical future discount is irrelevant to what he actually paid.

Comet Encke orbits the sun every 65 years. Tariq's grandfather saw the Comet when he was 48 years old. Tariq saw the comet a second time when he was two times the age his grandfather was when he saw the Comet. How old was Tariq when he saw the Comet for the first time?
Comet Encke orbits the sun every 65 years. Tariq's grandfather saw the Comet when he was 48 years old. Tariq was born 15 years after his grandfather first saw the Comet. Tariq saw the comet a second time when he was two times the age his grandfather was when he saw the Comet. How old was Tariq when he saw the Comet for...
Tariq saw the Comet for the second time when he was 48 years * 2= 96 years old. Comet Encke can be seen every 65 years, so Tariq saw the comet for the first time when he was 96 years - 65 years = 31 years old. #### 31
31
Tariq was born 15 years after his grandfather first saw the Comet.
The question asks for Tariq's age when he first saw the comet, which is determined entirely by the comet's 65-year orbit period and Tariq's age at his second sighting. Tariq saw it a second time at age 2×48=96, and the comet orbits every 65 years, so his first sighting was at 96-65=31. When Tariq was born relative to h...

A juggler can juggle 420 balls. Half of the balls are tennis balls, and 1/3 of the tennis balls are teal. How many teal tennis balls are there?
A juggler can juggle 420 balls. Half of the balls are tennis balls, and 1/3 of the tennis balls are teal. The juggler recently added 30 new balls to his collection, but he can still only juggle 420 at a time. How many teal tennis balls are there?
tennis balls:420 * 1/2=210 teal tennis balls:210*1/3=70 balls #### 70
70
The juggler recently added 30 new balls to his collection, but he can still only juggle 420 at a time.
The question establishes that the juggler can juggle 420 balls, and this remains unchanged despite owning more balls. The fractions (half are tennis balls, 1/3 of those are teal) apply to the 420 balls he juggles. The extra 30 balls in his collection are irrelevant because the problem is about the 420 he juggles. The a...

If Uma and Ananya have 460 meters of fence between them, and they agree to split it with Ananya getting 100 meters more than Uma, how much is left over for Uma?
If Uma and Ananya have 460 meters of fence between them, and they agree to split it with Ananya getting 100 meters more than Uma, but Uma had already installed 30 meters of her own fence last year, how much is left over for Uma?
Let x be the amount of fence Uma gets and y be the amount Ananya gets. We know that y = x + 100, and y + x = 460. Substituting the first equation into the second equation, we get 2x+100=460 Subtracting the 100 from both sides, we get 2x=360 We divide each side by two, leaving x=180. This means Uma has 180 meters of fen...
180
but Uma had already installed 30 meters of her own fence last year
The question asks how much fence Uma gets from the current 460-meter split, not how much total fence she has or still needs to install. The 30 meters she installed last year is separate from this allocation. The split is: Uma gets x, Ananya gets x + 100, and x + (x + 100) = 460, so x = 180. The previously installed fen...

Ali works a 6-hour shift each day, 3 days a week. He earns ¥11 per hour and gets a ¥432 bonus each week if the company performs well. How much money did Ali make in July if the company performed very well for the whole month?
Ali works a 6-hour shift each day, 3 days a week. He earns ¥11 per hour, which was raised from ¥9 per hour earlier that year, and gets a ¥432 bonus each week if the company performs well. How much money did Ali make in July if the company performed very well for the whole month?
In a day, Ali makes 6 * 11 = ¥66 If he works 3 days a week, the total number of days for the whole month is 3 * 4= 12 days. Since he makes ¥66 per day, the total amount for the whole month is 12 * 66= ¥792. He also got a 432 * 4 = ¥1728 bonus because the company performed well in all the weeks of July. At the end of Ju...

The question asks how much Ali made in July. His current hourly rate is stated as ¥11/hour, which is what he earns during July. What his rate used to be earlier in the year is irrelevant to his July earnings. This mirrors the inflation example from the paper — past prices don't affect current calculations. The temptati...

Riverside Academy is holding graduation in their Gymnasium this year which has space for 4100 people. After accounting for 650 seats for graduates and 200 seats for faculty attending, how many tickets would each graduate receive to give to their friends and family if the tickets are split equally?
Riverside Academy is holding graduation in their Gymnasium this year which has space for 4100 people. After accounting for 650 seats for graduates and 200 seats for faculty attending, how many tickets would each graduate receive to give to their friends and family if the tickets are split equally, given that 120 of the...
Add graduate and faculty seats together. 650 + 200 = 850 seats for faculty and graduates Minus seats for faculty and graduates from total seats allowed. 4100 - 850 = 3250 remaining seats. Divide remaining seats by the number of graduates. 3250/650 = 5 tickets #### 5

given that 120 of the graduates will also have reserved parking spots in the adjacent lot
The question asks about splitting remaining seat tickets equally among graduates. Reserved parking spots are in a separate lot and are not seats in the Gymnasium, so they don't affect the seat count or the number of graduates. The calculation remains (4100 - 650 - 200) / 650 = 3250 / 650 = 5.

There are 195 second-graders at Maple Grove School. 59 of them are girls. On Tuesday, 3 second-grade girls and 2 second-grade boys were absent. How many second grade boys were at Maple Grove School on Tuesday?
There are 195 second-graders at Maple Grove School. 59 of them are girls. On Tuesday, 3 second-grade girls and 2 second-grade boys were absent. Additionally, 4 first-graders joined the second-grade classes for a reading buddy program that morning. How many second grade boys were at Maple Grove School on Tuesday?
Of the 195 second graders, 59 are girls, so 195 students - 59 girls = 136 boys. On Tuesday there were 136 boys - 2 absent = 134 boys. #### 134

Additionally, 4 first-graders joined the second-grade classes for a reading buddy program that morning.
The question asks how many second-grade boys were at school on Tuesday. The first-graders joining the classes are not second-graders, so they should not be counted. However, the clause tempts the solver to add 4 (or some portion of 4) to the count of students present, since these children were physically in the second-...

Chen can peel 12 shrimps a minute and saute 30 shrimps in 11 minutes. How long will it take her to peel and saute 60 shrimps?
Chen can peel 12 shrimps a minute and saute 30 shrimps in 11 minutes. When she first started cooking, she could only peel 8 shrimps a minute. How long will it take her to peel and saute 60 shrimps?
First find how long it takes Chen to peel the shrimp: 60 shrimp / 12 shrimp/minute = 5 minutes Then find how many batches of shrimp she needs to cook: 60 shrimp / 30 shrimp/batch = 2 batches Then multiply the number of batches by the time per batch to find the total cook time: 2 batches * 11 minutes/batch = 22 minutes ...

When she first started cooking, she could only peel 8 shrimps a minute.
The question asks how long it will take her (now) to peel and saute 60 shrimps. Her current peeling rate is clearly stated as 12 shrimps per minute. Her past slower rate of 8 shrimps per minute is irrelevant to her current performance. The answer remains 5 minutes peeling (60÷12) + 22 minutes sautéing (2 batches × 11 m...

The Smith family is busy making cupcakes. So far, they've made 7225 cupcakes. They have 2303 peanut butter cupcakes, 1218 lemon cupcakes, and some blueberry cupcakes. They plan to give away 450 of the blueberry cupcakes to their neighbors later today. How many blueberry cupcakes have they made?
The total number of pieces of peanut butter and lemon cupcakes is 2303 + 1218 = 3521. Therefore, they made 7225 - 3521 = 3704 blueberry cupcakes. #### 3704

They plan to give away 450 of the blueberry cupcakes to their neighbors later today.
The question asks how many blueberry cupcakes they have MADE, not how many they will have after giving some away. The total number made is still 7225 - 2303 - 1218 = 3704, regardless of future plans to give some away.

A building is made out of 3 orange bricks, eight times as many pink bricks, and an unknown number of green bricks. If there are 48 bricks in the building in total, but 5 of the pink bricks were recycled from a previous building, how many green bricks are there?
There are 3*8 = 24 pink bricks in the building. There are 48-3-24 = 21 green bricks in the building. #### 21

but 5 of the pink bricks were recycled from a previous building
The question asks how many green bricks there are based on the total count of bricks. Whether some pink bricks were recycled or new doesn't change the number of pink bricks (still 8 × 3 = 24). The recycled status is about the origin of the bricks, not the quantity. So green = 48 - 3 - 24 = 21 remains unchanged. However...

GSM-NoOp (audited)

NoOp distractor clauses for GSM-Symbolic questions, audited for genuine irrelevance by an independent model (GPT-5.5), plus per-model evaluation results.

Accompanies the post Revisiting GSM-Symbolic: Do 2026 Frontier Models Still Fail at Confounded Grade School Math? and the code at github.com/BenSturgeon/gsm-symbolic-revisited.

Why

The GSM-Symbolic paper (Mirzadeh et al., Apple, ICLR 2025) reported that adding an irrelevant "NoOp" clause collapses LLM accuracy (~25–65 pp). Apple did not release the NoOp set. We regenerate one and audit each distractor for true irrelevance with a model from a different family than the generator, to separate "genuinely irrelevant" distractors from merely ambiguous ones. On the audited set the drop essentially vanishes (0–4 pp, not distinguishable from zero) for Opus 4.6, Haiku 4.5, and GPT-4o.

Contents

  • GSM_symbolic_100x10.jsonl — the source subset (100 templates × 10 instances) drawn from Apple's GSM-Symbolic.
  • GSM_noop_100.jsonl — 945 distractor clauses (one per question; malformed generations dropped), generated by Claude Opus 4.6. Fields include original_question, question (with distractor), added_clause, gold_answer.

  • GSM_noop_100_audit_opus.jsonl — Claude Opus 4.6 verdict (robustness cross-check; Cohen's κ = 0.32 vs GPT-5.5).
  • GSM_noop_100_filtered_gpt55.jsonl — the 117 distractors GPT-5.5 calls TRULY_IRRELEVANT (primary audited set).
  • GSM_noop_100_filtered_opus.jsonl — the 338 Opus keeps.
