He is washing 10 ounces of shirts because 2 x 5 = 10. He is washing 6 ounces of socks because 3 x 2 = 6. He is already washing 34 ounces of clothes because 10 + 10 + 8 + 6 = 34. He can wash 16 more ounces because 50 - 34 = 16. He can wash 4 pairs of underwear because 16 / 4 = 4.
The answer: 4
Reverse engineering the question: Tony's dad is very strict about the washing machine and family members are only allowed to wash 50 total ounces of clothing at a time. Tony doesn't want to break the rules, so he weighs his clothes and finds that a pair of socks weighs 2 ounces, underwear weighs 4 ounces, a shirt weighs 5 ounces, shorts weigh 8 ounces, and pants weigh 10 ounces. Tony is washing a pair of pants, 2 shirts, a pair of shorts, and 3 pairs of socks. How many more pairs of underwear can he add to the wash and not break the rule?


Reasoning and answer: Paul caught 5 fish 12 / 2 = 6 times that day. So he was able to catch in total 6 * 5 = 30 fish.
The answer: 30
What was the question?
Question: Paul goes fishing every Saturday. Last week he was able to catch 5 fish for every 2 hours he was fishing. How many fish did he catch when he was fishing for 12 hours?


One - third of the fruit: 78 / 3 = 26 kiwis. The rest are strawberries: 78 - 26 = 52. There are 52 strawberries in the crate.
The answer: 52
Reverse engineering the question: There are 78 pieces of fruit in a crate. One-third of the box contains kiwi. The rest are strawberries. How many strawberries are there?


Reasoning and answer: Without the first 10 snowflakes, there are 58 - 10 = 48 snowflakes needed. 48 / 4 = 12 5 - minute intervals are needed to get the additional snowflakes. 12 * 5 = 60 minutes passed.
The answer: 60
What was the question?
Question: There were 10 snowflakes at first. It snowed an additional 4 snowflakes every 5 minutes. How many minutes passed before there were 58 snowflakes?


If in eight years Brian will be 40 years old, he is currently 40 - 8 = 32 years old. Since Christian is twice as old as Brian, he is 2 * 32 = 64 years old. In 8 years, Christian will be 64 + 8 = 72 years old.
The answer: 72
Reverse engineering the question: Christian is twice as old as Brian. In eight more years, Brian will be 40 years old. How old will Christian be in eight years?


Together, they picked 30 * 3 = 90. There are 40 + 28 = 68 accounted for. Then Layla picked 90 - 68 = 22.
