Reasoning and answer: Teresa has 49 pencils because 14 + 35 = 49. Teresa gives away 39 pencils because 49 - 10 = 39. Each sibling gets 13 pencils because 39 / 3 = 13.
The answer: 13
What was the question?
Question: Teresa is collecting pencils. She has 14 colored pencils and 35 black pencils.

Five dozens of people is equal to 5 x 12 = 60. 60 x 2 = 120 cans of soda are needed. So, this means 120 / 10 = 12 boxes of soda must be purchased. Thus, it will amount to $2 x 12 = $24. Therefore, each family member will pay $24 / 6 = $4.
The answer: 4
Reverse engineering the question: Five dozens of people are attending your family reunion. Your family was assigned to bring the cans of soda. Each box of soda contains 10 cans and costs $2 per box. It was assumed that each person can consume 2 cans of soda. If you are six in the family and agreed to pay equally for the cost, how much will each of your family members pay?


Reasoning and answer: He has consumed 7 * 50 = 350 calories from the cookies. He needs to consume 500 - 350 = 150 more calories. He should eat 150 / 15 = 10 crackers.
The answer: 10

Question: Crackers contain 15 calories each and cookies contain 50 calories each. If Jimmy eats 7 cookies, how many crackers does he need to eat to have consumed a total of 500 calories?


After Smith gave him $200, Randy had 2000 + 1200 = 3200 dollars. Randy had 3200 - 200 = 3000 dollars at first.
The answer: 3000
Reverse engineering the question: Randy had some money. Smith gave him another $200. Randy then gave Sally $1,200 and kept the rest. If Randy has $2000 left, how much money, in dollars, did Randy have at first?


Reasoning and answer: First add all Janet's grade for the first semester of college: 90 + 80 + 70 + 100 = 340. Then divide that number by 4 to find her average grade: 340 / 4 = 85. Then subtract her semester 2 average to find the difference: 85 - 82 = 3.
The answer: 3
What was the question?
