Reasoning and answer: Per week, one cow produces 108 liters / 6 cows = 18 liters / cow. The cows produced 2160 liters of milk over 5 weeks. So we have 2160 liters / 18 liters / cow = 120 cows. Further, we have to divide 120 cows / 5 weeks = 24 cows.
The answer: 24

Over the movies run it made 120 * 3.5 = 420 million. So the production company made 420,000,000 * .6 = $252,000,000. So they got a profit of 252,000,000 - 60,000,000 = $192,000,000.
The answer: 192000000
Reverse engineering the question: A new movie gets released and makes $120 million in the box office for its opening weekend. It ends up making 3.5 times that much during its entire run.

Reasoning and answer: Five cupcakes cost 5 x $2 = $10. Six doughnuts cost 6 x $1 = $6. Four slices of apple pie cost 4 x $2 = $8. And, fifteen cookies cost 15 x $0.60 = $9. Therefore, Sophie spends $10 + $6 + $8 + $ 9 = $33.
The answer: 33
What was the question?
Question: Sophie buys five cupcakes at $2 each, six doughnuts at $1 each, four slices of apple pie at $2 per slice, and fifteen cookies at $0.60 each. How much does she spend in all?


If he babysits for 2 hours at $7 per hour, he will earn 2 * 7 = $14. This week he will earn $5 allowance, $10 mowing the lawn and $14 from babysitting for a total of 5 + 10 + 14 = $29. If we add the $29 he will earn to his $65 savings, he will have a total of 29 + 65 = $94. The bike costs $100 and he will have $94 leaving $100 - $94 = $6 more that he will need to earn.
The answer: 6
Reverse engineering the question: Zach is saving his money to buy a brand new bike that costs $100. His weekly allowance is $5. His parent will pay him an extra $10 to mow the lawn. His neighbor will pay him $7 per hour to babysit their son. He has already saved up $65. He'll receive his allowance on Friday and he's planning on babysitting for 2 hours this Saturday after he mows the lawn. How much more money does Zach need to earn before he can buy the bike?


Reasoning and answer: First subtract the 300 MB Elsa spent on YouTube: 500 MB - 300 MB = 200 MB. Then multiply 200 MB by 2 / 5th to find out how much data Elsa spent on Facebook: 200 MB * 2 / 5 = 80 MB. Finally, subtract the data Elsa spent on Facebook from the 200 MB: 200 MB - 80 MB = 120 MB.
The answer: 120
What was the question?
Question: Elsa gets 500 MB of cell phone data each month. If she spends 300 MB watching Youtube and 2/5 of what's left on Facebook, how many MB of data does she have left?


Reasoning and answer: The total square footage from the three bedrooms is 3 * 400 = 1200 square feet. The total square footage of the house is 1200 + 600 = 1800 square feet. Henrietta needs 1800 / 600 = 3 gallons of paint.
