If Sue has 48 nuts, and Harry has twice as many nuts as Sue, Harry has 2 * 48 = 96 nuts. Bill has 6 times as many nuts as Harry, and since Harry has 96 nuts, Bill has 96 * 6 = 576 nuts. Combined, Bill and Harry have 576 + 96 = 672 nuts.
The answer: 672
Reverse engineering the question: Bill has 6 times as many nuts as Harry, and Harry has twice as many nuts as Sue. If Sue has 48 nuts, how many do Bill and Harry have combined?


Reasoning and answer: By adding together Monday and Tuesday, Saah has 20 + 18 = 38 pencils. On Wednesday, she buys 3 * 18 = 54 pencils. All together, Sarah has 38 + 54 = 92 pencils.
The answer: 92
What was the question?
Question: Sarah buys 20 pencils on Monday. Then she buys 18 more pencils on Tuesday. On Wednesday she buys triple the number of pencils she did on Tuesday. How many pencils does she have?


Jasmine swims 5 days a week. The number of laps per week is 12 laps / day * 5 days / week = 60 laps / week. In five weeks, she swims 5 weeks * 60 laps / week = 300 laps.
The answer: 300
Reverse engineering the question: Jasmine swims 12 laps every afternoon, Monday through Friday. How many laps does she swim in five weeks?


Reasoning and answer: Janelle has 6 bags * 10 blue marbles = 60 marbles. Janelle has a total of 26 green marbles + 60 blue marbles = 86 marbles. Janelle gave away a gift of 6 green + 8 blue marbles = 14 marbles. Janelle has a final amount of 86 marbles - 14 marbles = 72 marbles.
The answer: 72
What was the question?
Question: Janelle had 26 green marbles. Then she bought 6 bags of blue marbles. There were 10 marbles in each bag. She created a gift of 6 green marbles and 8 blue marbles and gave it to a friend. How many marbles does Janelle have now?


A scientific calculator costs $8 x 2 = $16. A graphing calculator costs $16 x 3 = $48. So, she spent $8 + $16 + $48 = $72 for the three calculators. Therefore, the math teacher received $100 - $72 = $28 change.
The answer: 28
Reverse engineering the question: A math teacher had $100 to buy three different types of calculators. A basic calculator costs $8. A scientific calculator costs twice the price as the basic while a graphing calculator costs thrice the price as the scientific. How much change did she receive after buying those three different types of calculators?


There are 80 cherries in a pound and she needs 3 pounds to make a pie so she needs 80 * 3 = 240 cherries. It takes her 10 minutes to pit a unit of 20 cherries. She has 240 / 20 = 12 units of cherries to pit. It takes 10 minutes to pit a unit of cherries and she has 12 units so it will take her 10 * 12 = 120 minutes. 60 minutes are in 1 hour and it takes her 120 minutes so that’s 120 / 60 = 2 hours.
The answer: 2
Reverse engineering the question:
To make a cherry pie, Veronica needs 3 pounds of pitted cherries. There are 80 single cherries in one pound of cherries.  It takes 10 minutes to pit 20 cherries. How many hours will it take Veronica to pit all the cherries?
