He pays 5 * 5 = $25 for buying crayons. He pays 10 * 5 = $50 for buying books. He pays 3 * 5 = $15 for buying calculators. The change he has for buying bags is 200 - 25 - 50 - 15 = $110. The number of bags he can buy is 110 / 10 = 11 bags.
The answer: 11
Reverse engineering the question: Bruce buys 5 packs of crayons at $5 each, 10 books at $5 each, and 3 calculators at $5 each. If he has $200, how many bags can he buy with the change if one costs $10 each?


Reasoning and answer: He can buy 6 small bags because 24 / 4 = 6. These give him 300 balloons, because 6 x 50 = 300. He can buy 4 medium bags because 24 / 6 = 4. These give him 300 balloons because 4 x 75 = 300. He can buy 2 extra large bags because 24 / 12 = 2. This gives him 400 balloons because 2 x 200 = 400. 400 is the most he can buy because 400 is greater than 300.
The answer: 400

Question: Mark wants to have a water balloon fight with his friends. He goes to the store to buy balloons and sees that they sell small bags for $4, medium bags for $6 and extra large bags for $12. He has $24 and wants to get the most balloons as possible. If the $4 bags contain 50 balloons, the $6 bags contain 75 balloons and the $12 bags contain 200 balloons, what is the greatest number of balloons he can buy?


Mary took 10 + 6 = 16 chickens. John took 16 + 5 = 21 chickens. John took 21 - 10 = 11 more chickens than Ray.
The answer: 11
Reverse engineering the question: The Grey's bought several chickens at a sale. John took 5 more of the chickens than Mary took. Ray took 6 chickens less than Mary. If Ray took 10 chickens, how many more chickens did John take than Ray?


Reasoning and answer: He pays the minor characters 15000 * 4 = $60,000. The major characters each get 15000 * 3 = $45,000. So he pays the main characters 45,000 * 5 = $225,000. So in total he pays 225,000 + 60,000 = $285,000.
The answer: 285000

Ivory has 8 + 4 = 12 riddles. Taso has 12 * 2 = 24 riddles.
The answer: 24
Reverse engineering the question: Ivory got four more riddles than Josh did. Taso got twice as many riddles as Ivory did. If Josh has 8 riddles, how many riddles does Taso have?


Jake drank 8 / 2 = 4 shots. So he drank 4 * 1.5 = 6 ounces of vodka. That means he drank 6 * .5 = 3 ounces of pure alcohol.
The answer: 3
Reverse engineering the question:
Jake splits 8 shots of vodka with his friend. Each shot of vodka is 1.5 ounces. If the vodka is 50% pure alcohol, how much pure alcohol did Jake drink?
