They had to recover 3 + 2 = 5 animals. So it took 5 * 2 = 10 hours to recover everyone.
The answer: 10
Reverse engineering the question: 3 lions and 2 rhinos escape from the zoo. If it takes 2 hours to recover each animal how long did the zoo spend recovering animals?


Reasoning and answer: Emma had $2000 - $400 = $1600 left after buying furniture. Emma gave Anna 3 / 4 * $1600 = $1200. So, Emma is left with $1600 - $1200 = $400.
The answer: 400
What was the question?
Question: Emma got $2000 from the bank. She bought $400 of furniture and gave 3/4 of the rest to her friend Anna. How much is left with Emma?


On the second day, Mr. and Mrs. Hugo traveled 200 x 3 / 4 = 150 miles. They traveled a total of 200 + 150 = 350 miles in the first two days. On the third day, they traveled 350 x 1 / 2 = 175 miles. So, Mr. and Mrs. Hugo traveled a total of 200 + 150 + 175 = 525 miles for 3 days.
The answer: 525
Reverse engineering the question: Mr. and Mrs. Hugo went on a road trip. On the first day, they traveled 200 miles. On the second day, they traveled 3/4 as far. On the third day, they traveled 1/2 as many miles as the first two days combined. How many miles did they travel for 3 days?


Reasoning and answer: Let x represent the number of Chevys. Fords:3 + 2x. Buicks:4(3 + 2x) = 12 + 8x. Total:x + 3 + 2x + 12 + 8x = 301. 11x + 15 = 301. 11x = 286. x = 26. Buicks:12 + 8(26) = 220.
The answer: 220
What was the question?
Question: Jim collects model cars, and he has 301 models total. Jim has 4 times as many Buicks as Fords, and 3 more than twice the number of Fords than Chevys. How many Buicks does Jim have?


Twice as many tomatoes as mushrooms is 3 * 2 = 6 tomatoes. Four times as many pickles as tomatoes is 4 * 6 = 24 pickles. Four times as many bacon bits as pickles is 24 * 4 = 96 bacon bits. One third of 96 is 96 / 3 = 32 red bacon bits.
The answer: 32
Reverse engineering the question: At the salad bar, Grandma put three mushrooms on her salad. She also added twice as many cherry tomatoes as mushrooms, 4 times as many pickles as cherry tomatoes, and 4 times as many bacon bits as pickles. If one third of the bacon bits were red, than how many red bacon bits did Grandma put on her salad?


Starting with $100, he paid $20 to Colin, leaving him with $100 - $20 = $80. Twice as much as $20 is 2 * $20 = $40. Thus, he paid $40 to Helen, leaving him with $80 - $40 = $40. Half as much to Benedict as he had paid to Helen is $40 / 2 = $20. Thus, he paid $20 to Benedict, leaving him with $40 - $20 = $20 after paying off all debts.
The answer: 20
Reverse engineering the question:
Ian won $100 in the lottery. He decided to use the money to pay off debts. He paid $20 to Colin. He then paid twice as much to Helen, as he had paid to Colin. Then finally, he paid half as much to Benedict, as he had paid to Helen. How much money, in dollars, does he have left after paying off debts?
