The five boxes have a total of 5 x 8 = 40 bags of balloons. So, there are 40 x 12 = 480 balloons.
The answer: 480
Reverse engineering the question: A party store ordered 5 boxes of balloons. Each box contains 8 bags of balloons, and there are 12 balloons in each bag. How many balloons are there?


Reasoning and answer: Between grapes and mangoes, we have 13 + 20 = 33 crates. The remaining crates are passion fruits, so we have 50 - 33 = 17 crates of passion fruit.
The answer: 17
What was the question?
Question: Kevin is a fruit vendor. He always sells a total of 50 crates of fruit per week. Last week he sold 13 crates of grapes, 20 crates of mangoes, and the rest were passion fruits. How many passion fruit crates did he sell?


Kris has 12 / 4 = 3 turtles. Trey has 3 * 7 = 21 turtles. Trey has 21 - 12 = 9 more turtles than Kristen.
The answer: 9
Reverse engineering the question: Trey has 7 times as many turtles as Kris. Kris has 1/4 as many turtles as Kristen has. How many more turtles does Trey have than Kristen, if Kristen has 12?


Reasoning and answer: On the third day, there were one - third of the number of bedbugs as the fourth day, so there were 810 / 3 = 270 bedbugs. On the second day, there were one - third of the third day’s bedbugs, so there were 270 / 3 = 90 bedbugs. On the first day, there were 90 / 3 = 30 bedbugs in the group to start with.
The answer: 30
What was the question?
Question: A group of bedbugs infested an old mattress. Every day, the number of bedbugs would triple. After four days, there were 810 bedbugs burrowing into the mattress. How many bedbugs did the group start with?


The first dog walks 14 miles in a week because 7 x 2 = 14. The second dog walks 56 miles in a week because 70 - 14 = 56. The second dog walks an average of 8 miles a day because 56 / 7 = 8.
The answer: 8
Reverse engineering the question: Bingo has two dogs. On average, they walk a total of 70 miles a week. The first dog walks an average of 2 miles a day. How many miles a day does the other dog average?


He buys 10 / 1.25 = 8 notepads. That means he buys 8 * 60 = 480 pages.
The answer: 480
Reverse engineering the question:
Bart buys $10 of notepads for $1.25 each. They have 60 pages each. How many pages did he buy?
