Reasoning and answer: First find the number of crabs Max can get by dividing the number of coconuts by the exchange rate with crabs: 342 coconuts / 3 coconuts / crab = 114 crabs. Then divide the number of crabs by the exchange rate with goats: 114 crabs / 6 crabs / goat = 19 goats.
The answer: 19
What was the question?
Question: Max can trade 3 coconuts for a crab and 6 crabs for a goat. If he has 342 coconuts and he wants to convert all of them into goats, how many goats will he have?


Today, Grace is 3 + 1 = 4 years old. So, Diana is 4 * 2 = 8 years old today.
The answer: 8
Reverse engineering the question: Diana is twice as old as Grace is today. If Grace turned 3 a year ago, how old is Diana today?

He bought 20 * 1.5 = 30 pounds of soap. That cost 30 * .5 = $15.
The answer: 15
Reverse engineering the question: John buys 20 bars of soap each weighing 1.5 pounds for $.5 per pound. How much money did he spend on soap?


Reasoning and answer: Michael cleans himself 3 times a week because 2 + 1 = 3. He cleans himself 156 times 52 weeks because 52 x 3 = 156.
The answer: 156
What was the question?
Question: To get clean, Michael takes a bath twice a week and a shower once a week. How many total times does he clean himself in 52 weeks, which is about one year?


Reasoning and answer: Week 1:600 / 2 = 300. 600 - 300 = 300 pages remain. Week 2:300(.30) = 90 pages. 300 - 90 = 210 pages remain. Week 3:210 pages.
The answer: 210
