He watched 2 * 20 = 40 minutes of Jeopardy. Wheel of Fortune is 2 * 20 = 40 minutes each. So he watched it for 40 * 2 = 80 minutes. So he watched 40 + 80 = 120 minutes of TV. That means he watched 120 / 60 = 2 hours of TV.
The answer: 2
Reverse engineering the question: James watched 2 episodes of Jeopardy and 2 episodes of Wheel of Fortune. Jeopardy is 20 minutes and Wheel of Fortune is twice as long. How many hours did he watch TV?


Reasoning and answer: Oranges = 12 * 150 = 1800. Nectarines = 16 * 30 = 480. 1800 + 480 = 2280. There are 2280 pieces of fruit in total.
The answer: 2280
What was the question?
Question: There are 12 crates that each contain 150 oranges. There are 16 boxes that each hold 30 nectarines. How many pieces of fruit are in the crates and the boxes in total?


The number of people who took only wine is the difference between the number of people who took wine and those who took wine and soda which is 26 - 17 = 9 people. In the same manner, the number of people who took only soda is 22 - 17 = 5 people. Therefore the total number present is the sum of those who took wine only, those who took soda only and those who took both which is 9 + 5 + 17 = 31 people.
The answer: 31
Reverse engineering the question: At a gathering, it was reported that 26 people took wine, 22 people took soda, and 17 people took both drinks. If each person could have taken one or more drinks regardless of what was reported, how many people altogether were at the gathering?


Reasoning and answer: Total amount spent for athletic shoes and sportswear is $200 + $250 = $450. The price of the racket is $750 - $450 = $300.

What was the question?
Question: John bought a tennis racket. He also bought sneakers that cost $200 and a sports outfit that cost $250. He spent a total of $750 for all those items. What was the price of the racket?


First find the total amount of time Dan spends digging adult graves: 3 hours / grave * 5 graves = 15 hours. Then add the time to dig the child's grave to find the total time he spends digging: 15 hours + 2 hours = 17 hours.
The answer: 17
Reverse engineering the question: Dan is digging graves for a family killed by COVID-19. If it takes Dan 3 hours to dig an adult grave and 2 hours to dig a child's grave, how long does it take him to dig 5 adult graves and one child's grave?


Half of the books on the bottom section of the cart are mystery books, which means they are the same as the number of Western novels and biographies put together. So there are 5 + 6 = 11 mystery novels. Add them all together, and there are 12 history + 8 romance + 4 poetry + 11 mystery + 5 Western + 6 biographies = 46 books total.
The answer: 46
Reverse engineering the question:
Nancy, the librarian, is shelving books from the cart. She shelved 12 history books, 8 romance books, and 4 poetry books from the top section of the cart. Half the books on the bottom section of the cart were mystery books, which she quickly put back into place.
