All the animals have 4 legs. His 3 dogs will need 3 * 4 = 12 shoes. His 2 cats will need 2 * 4 = 8 shoes. His ferret will need 1 * 4 = 4 shoes. Olly will need 12 + 8 + 4 = 24 shoes.
The answer: 24
Reverse engineering the question: Olly wants to get shoes to protect his pets’ paws. He owns 3 dogs, 2 cats, and a ferret. How many shoes does he need?


Reasoning and answer: Sandra has 3 * 12 = 36 oranges. So, Emily has 7 * 36 = 252 oranges.
The answer: 252
What was the question?
Question: Emily has 7 times as many oranges as Sandra. Sandra has 3 times as many oranges as Betty. If Betty has 12 oranges, how many oranges does Emily have?


Brad weighs 145 + 5 = 150 pounds. Billy weighs 150 + 9 = 159 pounds.
The answer: 159
Reverse engineering the question: Billy weighs 9 pounds more than Brad. Brad weighs 5 pounds more than Carl. If Carl weighs 145 pounds, how much does Billy weigh, in pounds?


Reasoning and answer: Jerome bought 5 x 2 = 10 toy cars this month. So he bought a total of 5 + 10 = 15 toy cars. Therefore, Jerome had 40 - 15 = 25 toy cars originally.
The answer: 25
What was the question?
Question: Jerome bought 5 new toy cars last month. This month he bought twice as many so that he has 40 toy cars now. How many toy cars did Jerome have originally?


The sum of the weights of the three adults is 140 x 3 = 420 pounds. The sum of the weight of the two children is 64 x 2 = 128 pounds. So the total weight of the 5 people who are in the elevator is 420 + 128 = 548 pounds. This would mean that the next person's weight must not exceed 600 - 548 = 52 pounds.
The answer: 52
Reverse engineering the question: Three adults whose average weight is 140 pounds went first in the elevator. Two children whose average weight is 64 pounds also went inside. If an elevator sign reads “Maximum weight 600 pounds.", what is the maximum weight of the next person to get in the elevator so that it will not be overloaded?


For the first year, Joseph will have invested $1000 + ($100 * 12) = $2200. The interest calculated for the first year will be $2200 * 10% = $220. The total value of the investment for the first year will be $2200 + $220 = $2420. For the second year, the total invested will be $2420 + ($100 * 12) = $3620. The interest calculated after the second year will be $3620 * 10% = $362. Therefore, Joseph's investment in the mutual fund will be worth $3620 + $362 = $3982.
The answer: 3982
