Reasoning and answer: Johanna had 21 turtles - 5 turtles = 16 turtles. After 1 month, Owen was left with 21 turtles * 2 = 42 turtles. After 1 month, Johanna was left with 16 turtles / 2 = 8 turtles. After Johanna's donation, Owen was left with 42 turtles + 8 turtles = 50 turtles.
The answer: 50
What was the question?
Question: Owen bred 21 turtles, and Johanna has 5 fewer turtles than Owen. After 1 month, Owen has twice as many turtles as before and Johanna loses half of her turtles and donates the rest to Owen. How many turtles did Owen have?
The carpenters need to produce 75 / 50 = 1.5 times as many chairs in the same number of days. It will require 1.5 times as many carpenters to produce the extra chairs, so 8 * 1.5 = 12 carpenters will be required.
The answer: 12
Reverse engineering the question: If 8 carpenters can make 50 chairs in 10 days, how many carpenters are needed to make 75 chairs in 10 days?
Reasoning and answer: If Sierra is currently 30 years old, 10 times her age is 30 * 10 = 300. Twenty more than 10 times Sierra's age is 300 + 20 = 320. 320 is 40 less than ten times Diaz's age so 10 times Diaz's age is 320 + 40 = 360. If ten times Diaz's age is 360, Diaz is 360 / 10 = 36 years old. Twenty years from now, Diaz will be 20 + 36 = 56 years old.
The answer: 56

Question: 40 less than 10 times Diaz's age is 20 more than 10 times Sierra's age. If Sierra is currently 30 years old, how old will Diaz be 20 years from now?
A vendor bought each apple for $3 / 2 = $1.50. He will sell each apple at $10 / 5 = $2 each. His profit for each apple is $2 - $1.50 = $0.50. His total profit for 5 apples is $0.50 x 5 = $2.50. He bought each orange for $2.70 / 3 = $0.90. His profit for each orange is $1 - $0.90 = $0.10. His total profit for 5 oranges is $0.10 x 5 = $0.50. Therefore, his total profit for selling 5 apples and 5 oranges is $2.50 + $0.50 = $3.
The answer: 3
Reverse engineering the question: A vendor bought apples at 2 for $3 and plans to sell them at 5 for $10. He also bought 3 oranges for $2.70 and plans to sell them at $1 each. How much is his profit if he sells 5 apples and 5 oranges?
Reasoning and answer: The number of pants Isabella bought is 21 / 3 = 7 pairs of pants. The number of dresses Isabella bought is 18 / 3 = 6 dresses. The total number of pants and dresses Isabella bought is 7 + 6 = 13.
The answer: 13
What was the question?
Question: Isabella and Alexis went to the mall to buy some pants and dresses. Alexis bought 3 times more pants and dresses than Isabella. If Alexis bought 21 pairs of pants and 18 dresses, how many pairs of pants and dresses did Isabella buy in total?
Reasoning and answer: Toby gets 400 full rotations because 5 x 80 = 400. His friend get 404 rotations because 4 x 101 = 404. The winner rotated 404 objects because 404 > 400.
The answer: 404
What was the question?
Question:
Toby is in a juggling contest with a friend. The winner is whoever gets the most objects rotated around in 4 minutes. Toby has 5 baseballs and each one makes 80 rotations. His friend has 4 apples and each one makes 101 rotations. How many total rotations of objects are made by the winner?
