If a man buys 25 lollipops for $100 and sold them for $3 dollars determine his loss. | [
"$ 25",
"$ 60",
"$ 50",
"$ 35"
] | A | Cost of 25 lollipops = $90
Sold each lollipop for $3
So he sold 25 lollipops for $(25 × 3) = $75
Loss = $(100 – 75) = $25
Therefore, loss = $ 25.

A number when divided by 342 gives a remainder 47. When the same number if it divided by 19, what would be the remainder ? | [
"5",
"11",
"9",
"1"
] | C | On dividing the given number by 342, let k be the quotient and 47 as remainder.
Then, number – 342k + 47 = (19 x 18k + 19 x 2 + 9) = 19 (18k + 2) + 9.
The given number when divided by 19, gives (18k + 2) as quotient and 9 as remainder.

What is the difference between the compound interest on Rs.12000 at 20% p.a. for one year when compounded yearly and half yearly? | [
"399",
"288",
"120",
"133"
] | C | When compounded annually, interest
= 12000[1 + 20/100]1 - 12000 = Rs.2400
When compounded semi-annually, interest
= 12000[1 + 10/100]2 - 12000 = Rs.2520
Required difference = 2520 - 2400 = Rs.120

A certain car can travel 40 minutes on a gallon of gasoline at 60 miles per hour. If the car had started with a full tank and had 12 gallons of gasoline left in its tank at the end, then what percent of the tank was used to travel 80 miles at 60 mph? | [
"20%",
"25%",
"15%",
"14%"
] | D | Total time for travelling 80 miles @ 60 mph = 80/60 = 4/3 hour = 80 minutes.
Given, the car uses 1 gallon for every 40 minutes of driving @ 60 mph. Thus in 80 minutes it will use = 2 gallons. Thus, full tank = 2+12= 14 gallons ---> 2/14= 14% of the fuel used. E is the correct answer. | AquaRat_train |
