Reasoning and answer: To buy 100 pencils the school needs 100 * $1.80 = $180.00. Each ice pop sells for $1.50 but costs $.90 to make, for a net profit of $1.50 - $.90 = $.60. So in order to raise $180.00, the school will need to sell $180.00 / $.60 per ice - pop = 300 ice - pops.
The answer: 300
What was the question?
Question: To raise money, a school is selling ice-pops for $1.50. It costs 90 cents to make each pop, and the money from the pops will be used to buy pencils, which cost $1.80 each. How many pops must be sold to buy 100 pencils?


If the zoo would decide to import 4 new species, there would be 5 + 4 = 9 species in total. This would mean, that seeing each type of animal would take 9 * 6 = 54 minutes.
The answer: 54
Reverse engineering the question: At the zoo, there are 5 different types of animals. Seeing each animal type takes around 6 minutes. How much time would it take to see each animal type if the zoo decided to import 4 new species?


Reasoning and answer: Hammerhead shark:180 / 6 = 30. Great White:2(180 + 30) = 420 teeth.
The answer: 420
What was the question?

The frog eats 2 flies / day * 7 days / week = 14 flies a week. Betty catches flies in the morning and in the afternoon, for a total of 5 flies + 6 flies = 11 flies. But 1 fly escapes, leaving 11 flies - 1 fly = 10 flies. To get her frog's food for the whole week, Betty needs 14 flies - 10 flies = 4 more flies.
The answer: 4
Reverse engineering the question: Flies are Betty's frog's favorite food. Every day the frog eats 2 flies. Betty puts the flies she finds in a bottle. In the morning Betty catches 5 flies inside a bottle, and in the afternoon she catches 6 more, but when she removes the lid, one escapes. Betty wants to gather the whole week's food for her frog. How many more flies does she need?
