Bucket A has 10 more seeds than bucket B: so there are 10 seeds + 30 seeds = 40 seeds in bucket A. Bucket A and bucket B have 40 seeds + 30 seeds = 70 seeds together. If there are 100 seeds in all the buckets, then bucket C has 100 seeds - 70 seeds = 30 seeds.
The answer: 30
Reverse engineering the question: There are three buckets of seeds labeled A, B, and C with 100 seeds. There are ten more seeds in bucket A than in bucket B, and bucket B has 30 seeds. How many seeds are in bucket C?


Reasoning and answer: George has 18 - 6 = 12 stickers. Jerry has 12 * 3 = 36 stickers.
The answer: 36
What was the question?
Question: Jerry has three times as many stickers as George. George has 6 fewer stickers than his brother Fred. If Fred has 18 stickers, how many stickers does Jerry have?


Lee has 5 * 2 = 10 jellybeans. Tino has 10 + 24 = 34 jellybeans.
The answer: 34
Reverse engineering the question: Tino has 24 more jellybeans than Lee. Arnold has half as many jellybeans as Lee. If Arnold has 5 jellybeans, how many jellybeans does Tino have?


Reasoning and answer: She is in school for 40 hours because 5 x 8 = 40. She is in math class for 10 hours a week because 40 x .25 = 10.
The answer: 10
What was the question?
Question: Ruth goes to school 8 hours a day and 5 days a week. She is in math class 25% of this time. How many hours per week does she spend in math class?


Philip has 50 / 100 * 20 = 10 more ducks than cows. Which means he has 20 + 10 = 30 ducks. So Philip's cows and ducks sum up to 20 + 30 = 50 animals. If there are 50 cows and ducks, that means Philip has 1 / 5 * 50 = 10 pigs. In total Philip has 50 + 10 = 60 animals on his farm.
The answer: 60
Reverse engineering the question: Philip has a farm with animals. He has 20 cows, 50% more ducks. Philip also has as many pigs as one-fifth of ducks and cows in total. How many animals does Philip have on his farm?


Each of Tom's visits was 200 * .7 = $140 cheaper. So he paid $200 - $140 = $60 per visit. That means he paid $60 * 2 = $120. So he saved $200 - $120 = $80.
The answer: 80
Reverse engineering the question:
Tom cannot afford a normal doctor, so he goes to a discount clinic that is 70% cheaper.  It takes two visits, though, instead of 1.  A normal doctor charges $200 for a visit.  How much money does he save?
