Reasoning and answer: 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
What was the question?
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?
For the first 30 minutes, 3 * 2 = 6 cups of water came out. For the next 30 minutes, 3 * 2 = 6 cups of water came out. For the next hour, 6 * 4 = 24 cups of water came out. A total of 6 + 6 + 24 = 36 cups of water came out. Shawn had to dump water which left 36 / 2 = 18 cups of water.
The answer: 18
Reverse engineering the question: The water pressure of a sink has a steady flow of 2 cups per 10 minutes for the first 30 minutes. It still flows at 2 cups per 10 minutes for the next 30 minutes after. For the next hour, the water pressure maximizes to 4 cups per 10 minutes and stops. Shawn now has to dump half of the water away. How much water is left?
Reasoning and answer: After giving five games to Neil, Henry has 33 - 5 = 28 games left. Now, Neil has 28 / 4 = 7 games. Neil had 7 - 5 = 2 games at first.
The answer: 2

Question: Henry had 33 games, and he gave five of them to Neil. Now Henry has 4 times more games than Neil. How many games did Neil have at first?
First find the total payment James receives: $0.50 / mile * 600 miles = $300. Then find how many gallons of gas he needs to buy: 600 miles / 20 miles / gallon = 30 gallons. Then multiply that number by the price of gas per gallon to find the total cost of the gas: $4.00 / gallon * 30 gallons = $120. Then subtract that amount from James' earnings to find his profit: $300 - $120 = $180.
The answer: 180
Reverse engineering the question: James gets paid $0.50/mile to drive a truck carrying hazardous waste. He has to pay $4.00/gallon for gas and his truck gets 20 miles per gallon. How much profit does he make from a 600 mile trip?
Reasoning and answer: He buys 10 / 1.25 = 8 notepads. That means he buys 8 * 60 = 480 pages.
The answer: 480
What was the question?
Question: Bart buys $10 of notepads for $1.25 each. They have 60 pages each. How many pages did he buy?
Reasoning and answer: The first 8 years cost 8 * 10,000 = $80,000. The next 18 - 8 = 10 years. They cost 10000 * 2 = $20,000 per year. So they cost 20,000 * 10 = $200,000. So the cost was 200,000 + 80,000 = $280,000. Adding in the cost of tuition brings the cost to 250,000 + 280,000 = $530,000. Since John pays for half the cost of raising the child, he pays $530000 / 2 = 265000.
The answer: 265000

Question:
John pays for half the cost of raising a child. It cost $10,000 a year for the first 8 years and then twice that much per year until the child is 18. University tuition then costs $250,000. How much did it cost?
