Question: Company A and Company B merge. Company A receives 60% of the combined profits under the new merger, and company B receives 40% of the profits. If company B gets a total of $60000 in profit, how much does company A get?

Answer: 90000

Let the total profit of both companies be denoted by x. Therefore, 40% * x = 0.4 * x = $60000. So x = $60000 / 0.4 = $150000. If Company B gets 60 % of the profits, it gets 60% of $150000, which is 0.6 * $150000 = $90000.


Question: Musa is the class teacher of a class of 45 students. He wants to split them into three groups by age. If a third of the class is under 11 years, and two-fifths are above 11 but under 13, how many students will be in the third group (13 years and above)?

Answer: 12

The first group is a third of the class which is (1 / 3) * 45 = 15 students. There are 15 students in the first group, so there are 45 - 15 = 30 students. The second group is two - fifths of the class which is (2 / 5) * 45 = 18 students. There are 18 in the second group so there are 30 - 18 = 12 students left in the third group.


Question: It took Dad 5 more than twice as long to vacuum upstairs then to vacuum downstairs. He vacuumed for a total of 38 minutes. How many minutes did he vacuum upstairs?

Answer: 27

Let D = time in minutes to vacuum downstairs. Upstairs = 2D + 5 minutes. 3D + 5 = 38. 3D = 33. D = 11 minutes. Upstairs = (2 * 11) + 5 = 27 minutes. Dad took 27 minutes to vacuum upstairs.


Question: Ryan wants to take 5 peanut butter sandwiches to the beach. If each sandwich consists of 3 slices of bread how many slices does Ryan need to make 5 sandwiches?

Answer: 15

To make 1 sandwich, you need 3 slices so Ryan needs 1 * 3 = 3 slices to make one sandwich. Since it takes 3 slices to make a sandwich, and Ryan wants 5 sandwiches to take to the beach he needs 3 * 5 = 15 slices.


Question: Max fills up water balloons for 30 minutes at a rate of 2 water balloons every minute. Max’s friend Zach fills up water balloons for 40 minutes at a rate of 3 water balloons every minute. In the process, 10 of the water balloons pop on the ground. How many filled water balloons do Max and Zach have in total?

Answer: 170

Max fills 30 * 2 = 60 water balloons. Zach fills 40 * 3 = 120 water balloons. Max and Zach have a total of 60 + 120 - 10 = 170 water balloons.

Question: Tapanga and Corey have 66 candies together. However, Tapanga has 8 more candies than Corey. How many candies does Corey have?

Answer: 29

Let x = the total number of candies Corey has. x + 8 = the total number of candies Tapanga has. The equation for the total number of candies is x + (x + 8) = 66. Combining like terms, we get 2x + 8 = 66. Subtracting 8 from both sides, we get 2x = 58. Dividing both sides by 2, we get x = 29, so Corey has 29 candies.


Question: Nikola is saving up for a bag of ant food before he can start his ant farm. He wants 400 ants in his farm. Each ant needs 2 ounces of food. Every ounce of ant food costs $.1. Nikola is saving up by raking leaves. He charges $5 to start a job and then he charges by the leaf. Each leaf he rakes costs 1 penny. He finally saved up enough money after he raked 6,000 leaves. How many jobs did he complete?

Answer: 4

The ants will need 800 ounces of food because 400 x 2 = 800. The ant food will cost $80 because 800 x .1 = 80. He has earned $60 from the leaves he has raked because 6000 leaves * $0.01 / leaf = $60. He earned $20 from all his jobs because 80 - 60 = 20. He completed 4 jobs because 20 / 5 = 4.


Question: А Senior Center is hosting a bingo night. $2,400 in prize money will be given away. The first winner of the night will receive a third of the money. The next ten winners will each receive a 10th of the remaining amount. How many dollars will each of the next ten winners receive?

Question: Mark is filling a punch bowl that can hold 16 gallons of punch. He fills it part way, then his cousin comes along and drinks half the punch in the bowl. Mark starts to refill the bowl and adds 4 more gallons, but then his friend Sally comes in and drinks 2 more gallons of punch. After that, Mark has to add 12 gallons of punch to completely fill the bowl. How much punch did Mark initially add to the bowl?

Answer: 4

First, figure out how much punch was left in the bowl before Mark refilled it by subtracting the 12 gallons he added from the bowl's total capacity: 16 - 12 = 4 gallons. Next, figure out how much punch was in the bowl before Sally came along: 4 + 2 = 6 gallons. Next, figure out how much punch was in the bowl before Mark started to refill it: 6 - 4 = 2 gallons. Finally, multiply that amount by 2 to find out how much punch there was before the cousin drank half: 2 * 2 = 4 gallons.


Question: A sack of rice, which is 50 kilograms, costs $50. If David sells it for $1.20 per kilogram, how much will be his profit?

Answer: 10

David's revenue for the 50 kilograms of rice is $1.20 x 50 = $60. So, his profit is $60 - $50 = $10.


Question: In the honey shop, the bulk price of honey is $5 per pound and the minimum spend is $40 before tax. The honey is taxed at $1 per pound. If Penny has paid $240 for honey, by how many pounds has Penny’s purchase exceed the minimum spend?

Answer: 32

Including tax, a pound of honey costs 5 + 1 = 6 dollars. The minimum purchase equals 40 / 5 = 8 pounds of honey. Penny has bought 240 / 6 = 40 pounds of honey. Penny has exceeded the minimum purchase by 40 - 8 = 32 pounds.


Question: Lars owns a bakeshop. She can bake 10 loaves of bread within an hour and 30 baguettes every 2 hours. If she bakes 6 hours a day, how many breads does she makes?

Answer: 150

Lars can bake 10 x 6 = 60 loaves of bread every day. She can also bake 30 x 3 = 90 baguettes every day. Therefore the total bread she can bake is 60 + 90 = 150.


Question: We harvested 405 kg of apples. 90 kg were used to make fruit juice and 60 kg were given to a restaurant. The rest was sold in 5 kg bags and their sale brought in $408. What was the selling price of one bag of apples?

Answer: 8

The weight of apples used for juice and given to the restaurant is 60 + 90 = 150 kg. Thus 405 – 150 = 255kg worth of apples were sold in 5 kg bags. There were 255 / 5 = 51 bags sold. So each bag was sold for 408 / 51 = $8.


Question: In 5 years, Joey will be as old as Beth is now. If Joey is 9 now, how old was Joey when Beth was Joey's age now?

Question: A park has 50 benches with a capacity of 4 people each. On a Sunday afternoon, 80 people were sitting on the benches. What's the number of available spaces on the benches that other people can sit on before the carrying capacity of the benches is full?

Answer: 120

In the park, 50 benches with a capacity of four people each have a total capacity of 50 * 4 = 200 sitting spaces. If 80 people are already using spaces, the number of empty spaces is 200 - 80 = 120.


Question: Patricia and Geoffrey went fishing to feed their group of campers. They caught an eight-pound trout, six two-pound bass, and two twelve-pound salmon. If each person will eat two pounds of fish, how many campers can they feed?

Answer: 22

The bass weigh 6 * 2 = 12 pounds in all. The salmon weigh 2 * 12 = 24 pounds in all. The trout, bass, and salmon together weigh 8 + 12 + 24 = 44 pounds. Each camper will eat 2 pounds of fish, so Patricia and Jeffrey can feed 44 / 2 = 22 campers.


Question: It takes 10 minutes to wash a car, 15 minutes to change oil, and 30 minutes to change a set of tires. If mike washes 9 cars, changes the oil on 6 cars, and changes two sets of tires how many hours did he work?

Answer: 4

He spent 10 minutes * 9 cars = 90 minutes washing cars. He spent another 15 minutes * 6 cars = 90 minutes changing oil. He spent 2 cars * 30 minutes = 60 minutes changing tires. He spent 90 minutes + 90 minutes + 60 minutes = 240 minutes working. He spent 240 minutes / 60 minutes = 4 hours working.

Bogan served a total of 20 maggots. Bogan gave the beetles 10 maggots in the first feeding. Bogan gave the beetles 20 - 10 = 10 maggots in the second feeding.


Question: The largest room in Mrs. McAvoy's house is 45 feet wide and 30 feet long. The smallest room in that same house is 15 feet wide and 8 feet long. What is the difference in area between the largest room and the smallest room?

Answer: 1230

The area of the largest room is 45 ft x 30 ft = 1350 sq ft. The area of the smallest room is 15 ft x 8 ft = 120 sq ft. The difference between the two is 1350 sq ft - 120 sq ft = 1230 sq ft.


Question: Michael and Thomas are selling their lego collections. They agree to split any money they earn. They sell them based on how many circles are on top. Each circle costs 1 cent. They earned $5 each after selling 100 single pieces, 45 double pieces, 50 triple pieces and a number of quadruple pieces. How many quadruple pieces did they sell?

Answer: 165

They made $10 because 2 x 5 = 10. They made $1 off single pieces because 100 x .01 = 1. They made $.9 off double pieces because 45 x .02 = .9. They made $1.5 off triple pieces because 50 x .03 = 1.5. They earned $3.4 off the first three types because 1 + .9 + 1.5 = 3.4. They earned $6.6 off the quadruple pieces because 10 - 3.4 = 6.6. They sold 165 quadruple pieces because 6.6 / .04 = 165.


Question: Logan makes $65,000 a year. He spends $20,000 on rent every year, $5000 on groceries every year, and $8000 on gas every year. If he wants to have at least $42000 left, how much more money must he make each year?

Answer: 10000

Logan spends 20000 + 5000 + 8000 = 33000 a year. Logan has 65000 - 33000 = 32000 left a year. Logan needs to make 42000 - 32000 = 10000 more a year.


Question: Of 96 oranges, half were ripe. If 1/4 of the ripe oranges were eaten and 1/8 of the unripe oranges were eaten, how many were left eaten in total?

Answer: 78

There were 96 / 2 = 48 ripe oranges. 48 / 4 = 12 ripe oranges were eaten. 48 / 8 = 6 unripe oranges were eaten. There were 12 + 6 = 18 oranges eaten in total. There were 96 - 18 = 78 oranges left uneaten.


Question: Baking in batches of 65 cupcakes, Carla made 45 batches of cupcakes for her daughter's birthday party. She then took 5 cupcakes from each batch, and fed them to her dogs. If Carla's daughter had 19 friends and they shared the remaining cupcakes equally among them, including the daughter, calculate the number of cupcakes that each of Carla's daughter's friends ate.

Answer: 135

If Carla sampled 5 cupcakes from each batch and fed them to her dogs, each batch had 65 - 5 = 60 cupcakes afterwards. Since Carla made 45 batches of cupcakes for her daughter's birthday party, after removing the 5 cupcakes from each batch, Carla's daughter and her friends received 45 * 60 = 2700 cupcakes. The total number of people at the party is 19 friends + 1 daughter = 20. After sharing the cupcakes equally among them, Carla's daughter and her friends each received 2700 / 20 = 135 cupcakes.

How much money does Sally need to pay out of pocket, to buy every student a reading book?

Answer: 40

To purchase a book for each student, Sally needs: 30 x $12 = $360. She thus needs to pay $360 - $320 = $40 out of pocket.


Question: Harry is 50 years old. His father is currently 24 years older than he is. How old was his mother when she gave birth to him if she is younger than his father by 1/25 of Harry's current age?

Answer: 22

Harry's father is 50 years + 24 years = 74 years old. Harry's mother is 1 / 25 * 50 years = 2 years younger than his father. So she is currently 74 years - 2 years = 72 years old. So when Harry was born, she was 72 years - 50 years = 22 years old.


Question: Mark does a gig every other day for 2 weeks. For each gig, he plays 3 songs. 2 of the songs are 5 minutes long and the last song is twice that long. How many minutes did he play?

Answer: 280

He played 7 * 2 = 14 gigs. The long song was 5 * 2 = 10 minutes. So all the gigs were 5 + 5 + 10 = 20 minutes. So he played 14 * 20 = 140 minutes.


Question: There were 50 people on the city bus. At the first stop, 15 people got off. At the next stop 8 people got off and 2 got on. At the third stop, 4 people got off and 3 people got on. How many people are on the bus after the third stop?

Answer: 28

The bus started with 50 people – 15 who got off at the first stop = 35 people on the bus. At the second stop, 35 people on the bus – 8 who got off = 27 people. Then there were 27 people + 2 who got on = 29 people on the bus. At the third stop, 29 people on the bus – 4 who got off = 25 people on the bus. Then there were 25 people on the bus + 3 who got on = 28 people on the bus.


Question: In a certain school, 2/3 of the male students like to play basketball, but only 1/5 of the female students like to play basketball. What percent of the population of the school do not like to play basketball if the ratio of the male to female students is 3:2 and there are 1000 students?

Answer: 52

The students are divided into 3 + 2 = 5 parts where 3 parts are for males and 2 parts are for females. Each part represents 1000 / 5 = 200 students. So, there are 3 x 200 = 600 males. And there are 2 x 200 = 400 females. Hence, 600 x 2 / 3 = 400 males play basketball. And 400 x 1 / 5 = 80 females play basketball. A total of 400 + 80 = 480 students play basketball. Therefore, 1000 - 480 = 520 do not like to play basketball. The percentage of the school that do not like to play basketball is 520 / 1000 * 100 = 52.


Question: There are 15 cats in a shelter. One-third were adopted, and were replaced with twice the amount that were adopted. Later on, twice as many dogs showed up as there are cats. How many total animals are there in the shelter?

Answer: 60

15 / 3 = 5 cats were adopted out of 15. There were 15 - 5 = 10 cats left. 5 * 2 = 10 more cats were added. This makes 10 + 10 = 20 cats in the shelter. 20 * 2 = 40 dogs came into the shelter. There are now 20 + 40 = 60 animals in the shelter.

Question: Mr. Rainwater has some goats, 9 cows and some chickens. He has 4 times as many goats as cows and 2 times as many goats as chickens. How many chickens does he have?

Answer: 18

Let X be the number of chickens Mr. Rainwater has. He has 4 goats / cow * 9 cows = 36 goats on his farm. So he has 36 goats / 2 goats / chicken = 18 chickens.


Question: At camp Wonka, there are 96 campers. Two-thirds of the campers are boys, and the remaining one-third are girls. 50% of the boys want to toast marshmallows and 75% of the girls want to toast marshmallows. If each camper gets one marshmallow to toast, how many marshmallows do they need?

Answer: 56

The girls make up one - third of the campers, so there are 96 / 3 = 32 girls. The boys make up two - thirds of the campers, so there are 32 + 32 = 64 boys. There are 32 x 75% = 24 girls who want to toast marshmallows. There are 64 x 50% = 32 boys who want to toast marshmallows. They need 24 + 32 = 56 marshmallows.


Question: A factory decides to stop making cars and start making motorcycles instead. When it made cars, per month, it cost $100 for materials, they could make 4 cars, and they sold each car for $50. Now that they make motorcycles it costs $250 for materials, but they sell 8 of them for $50 each. How much more profit do they make per month selling motorcycles instead of cars?

Answer: 50

They sold $200 worth of cars each month because 4 x 50 = 200. They made $100 a month off cars because 200 - 100 = 100. They sold $400 worth of motorcycles each month because 8 x 50 = 400. They make $150 a month off motorcycles because 400 - 250 = 150. They make $50 more a month off motorcycles than cars because 150 - 100 = 50.


Question: Gwen received a $900 bonus at work and decided to invest this money in the stock market. She spent one-third of her bonus on stock A, one-third on stock B, and the remaining one-third on stock C.  After one year, stock A and stock B had doubled in value, while stock C had lost half of its value. At the end of the year, how much were Gwen's stocks worth, in dollars?

Answer: 1350

One - third of her bonus was $900 / 3 = $300. After one year, stock A doubled in value and was worth $300 * 2 = $600. After one year, stock B doubled in value and was worth $300 * 2 = $600. After one year, stock C had lost half its value and was worth $300 / 2 = $150. Altogether, at the end of the year, Gwen's stocks were worth $600 + $600 + $150 = $1350.


Question: James and John combine their friends lists. James has 75 friends. John has 3 times as many friends as James. They share 25 friends. How many people are on the combined list?

Answer: 275

John has 75 * 3 = 225 people on his friends list. So that means there are 225 + 75 = 300 people on the list. So once you remove duplicates there are 300 - 25 = 275 people.


Question: It takes Jennifer 20 minutes to groom each of her 2 long hair dachshunds. If she grooms her dogs every day, how many hours does she spend grooming her dogs in 30 days?

Answer: 20

She has 2 dogs and it takes 20 minutes to groom just 1 dog so it takes her 2 * 20 = 40 minutes per day to groom 2 dogs. In 30 days, she will have spent 30 * 40 = 1,200 minutes grooming her dogs. There are 60 minutes in an hour so she spends 1200 / 60 = 20 hours grooming her dogs.


Question: Jim decides to open up a bike shop. The most common repair he does is fixing bike tires. He charges $20 for this and it cost him $5 in parts. In one month Jim does 300 of these repairs. He also does 2 more complex repairs for $300 each and cost $50 in parts. He also sells $2000 profit worth of things from his retail shop. If rent and other fixed expense for the shop is $4000 a month how much profit did the shop make?

Answer: 3000

From each tire repair, he made 20 - 5 = $15 profit. So repairs made him a profit of 15 * 300 = $4500. The two complex repairs each made him 300 - 50 = $250 profit. So those added 250 * 2 = $500. So his total profit from everything was 4500 + 500 + 2000 = $7000. So he made a profit of 7000 - 4000 = $3000.


Question: Mary went to the store to buy fruit. Apples cost $1, oranges cost $2, and bananas cost $3. For every 5 fruits that customers buy, the store offers a $1 discount. Mary buys 5 apples, 3 oranges, and 2 bananas. How much will she pay?

Answer: 15

For 5 apples, Mary will pay 5 * 1 = 5 dollars. For 3 oranges, she will pay 3 * 2 = 6 dollars. For 2 bananas, she will pay 2 * 3 = 6 dollars. She bought 5 + 3 + 2 = 10 fruits. For 10 fruits, Mary gets a discount of 10 / 5 = 2 dollars. In total, the bill is 5 + 6 + 6 = 17 dollars. Subtracting the discount offered by the stores, Mary will pay 17 - 2 = 15 dollars.


Question: Mark deposited $88 in a bank. Bryan deposited $40 less than five times as much as Mark. How much did Mark deposit in the bank?

Question: Polly and Gerald went for a fun afternoon riding mini race cars at the munchkin track, which is a one-quarter mile circular track. Polly managed to circle the track 12 times in one half hour, but Gerald's car was malfunctioning, and he only moved at an average speed half of what Polly did. What speed did Gerald's car average, in miles per hour?

Answer: 3

Polly circled the one - quarter mile track 12 times in 0.5 hours at a speed of 12 / 0.5 = 24 circuits of the track per hour. 24 / 4 = 6 miles per hour. Gerald traveled at a speed half of what Polly traveled for an average speed of 6 / 2 = 3 miles per hour.


Question: Mathilda is determined to pay back the money she owes a friend so she decides to pay an initial installment of $125. If she still has 75% left to pay, how much did she owe originally?

Answer: 500

Percentage means per 100, so if she still owes 75%, she must have paid 100% - 75% = 25% of the original amount. 25% of the original amount = (25 / 100) * original amount = $125. Multiplying both sides by (100 / 25) gives: original amount = (100 / 25) * $125 = $500.


Question: A school is adding 5 rows of seats to the auditorium. Each row has 8 seats and each seat costs $30. A parent, being a seat manufacturer, offered a 10% discount on each group of 10 seats purchased. How much will the school pay for the new seats?

Answer: 1080

Ten seats amount to $30 x 10 = $300. So there is $300 x 10 / 100 = $30 discount for each 10 seats purchased. Thus, the total cost for every 10 seats is $300 - $30 = $270. The school is going to buy 5 x 8 = 40 seats. This means that the school is going to buy 40 / 10 = 4 sets of 10 seats. Therefore, the school will pay a total of $270 x 4 = $1080 for the new seats.


Question: Christi saw twice as many black bears as white bears and 40 more brown bears than black bears in a national park. If the number of black bears in the park is 60, calculate the population of bears in the park.

Answer: 190

If there are 60 black bears in the park and 40 more brown bears than black bears, there are 60 + 40 = 100 brown bears. The number of black and brown bears in the park is 100 + 60 = 160. Twice the number of black bears as white bears means 60 / 2 = 30 white bears. The population of bears in the national park is 30 + 160 = 190.


Question: Steve finds 100 gold bars while visiting Oregon. He wants to distribute his gold bars evenly to his 4 friends. If 20 gold bars were lost on the way back to San Diego, how many gold bars will each of his 4 friends get when he returns?

Question: An office has 90 workers. 2/3rds of them are men and the rest are women. The company hires 10 new employees and 100% of them are women. What is the total percentage of women in the company now?

Answer: 40

1 / 3rd of the workers before the new hires were women because 1 - (2 / 3) = 1 / 3. There were 30 women working for the company before the new hires.
