Reasoning and answer: As pajama sets are made up of a top and a bottom, there are 4 pajama sets * 2 = 8 articles of clothing from Adam's donation. In total, Adam is donating 4 pairs of pants + 4 jumpers + 8 pajama pieces + 20 t - shirts = 36 articles of clothing. Together, the 3 friends donate a total of 36 articles of clothing per friend * 3 friends = 108 articles of clothing. Adam changes his mind and takes back half, which means he is now actually donating 36 / 2 = 18 articles of clothing. There is therefore now a total of 108 + 18 = 126 articles of clothing being donated.
The answer: 126
What was the question?
Question: Adam’s wardrobe is too crowded so he decides to donate some of his clothes to a charity shop. He takes out 4 pairs of pants, 4 jumpers, 4 pajama sets (top and bottom), and 20 t-shirts, then asks his friends if they have anything they want to donate. 3 of his friends donate the same amount of clothing as Adam each. Then he takes another look over his clothing and decides that he actually wants to keep half of his clothes. How many articles of clothing are being donated in total?


Wallace already has 20 bags of jerky, so he needs to make 60 - 20 = 40 bags more. He can make 10 bags per day, so he needs 40 / 10 = 4 days to fulfill the customer’s order.
The answer: 4
Reverse engineering the question: Wallace runs a beef jerky company. The company dries the jerky low and slow, so one batch of jerky takes all night to make. Each batch can make 10 bags of jerky. Wallace received a customer order for 60 bags of jerky. If he has 20 bags of jerky already made, how many days will it be before he can fulfill the customer’s order?

The age difference between Beth and her sister is 18 - 5 = 13 years. Beth must be 13 x 2 = 26 to be twice her sister's age. Beth will be twice her sister's age in 26 - 18 = 8 years.
The answer: 8
Reverse engineering the question: If Beth is 18 years old and her little sister is 5, in how many years would she be twice her sister's age?


Reasoning and answer: The kingfisher caught 13 + 7 = 20 fish. The pelican and kingfisher caught 13 + 20 = 33 fish. The fisherman caught 3 x 33 = 99 fish. The fisherman caught 99 - 13 = 86 more fish than the pelican.
The answer: 86
What was the question?
Question: A pelican caught 13 fish and a kingfisher caught 7 more fish than the pelican. If a fisherman caught 3 times the total amount of fish the pelican and kingfisher caught, how many more fish did the fisherman catch than the pelican?


Reasoning and answer: 1 hour is 60 minutes, so 120 minutes is 120 / 60 = 2 hours. During one hour a fox can make 50 kilometers, so during two hours, he would be able to run 50 * 2 = 100 kilometers.
The answer: 100
What was the question?
Question:
A fox can run at the maximum speed of 50 kilometers per hour. Considering the fox would run at a constant speed, what distance would he make during 120 minutes?
