Sheila needs 3 + 2 = 5 pounds of flour. Together, they need 3 + 5 = 8 pounds of flour.
The answer: 8
Reverse engineering the question: Katie is making bread that needs 3 pounds of flour. Sheila is making another kind of bread that needs 2 more pounds of flour. How many pounds of flour do they need together?


Reasoning and answer: 60% of the students pay for the lunch because 100 - 40 = 60. 30 students pay for lunch because 50 x .6 = 30. These students pay $7 for their lunch because 210 / 30 = 7.
The answer: 7
What was the question?
Question: At a school, 40% of the students receive a free lunch. These lunches are paid for by making sure the price paid by the paying students is enough to cover everyone's meal. If it costs $210 to feed 50 students, how much do the paying students pay for lunch?


There were 6 x 8 = 48 bananas from the bunches with 8 bananas in a bunch. There were 5 x 7 = 35 bananas from the bunches with 7 bananas in a bunch. Therefore, Nathan had 48 + 35 = 83 bananas.
The answer: 83
Reverse engineering the question: Nathan bought one large box of bananas. He saw that there are six bunches with eight bananas in a bunch and five bunches with seven bananas in a bunch. How many bananas did Nathan have?


Reasoning and answer: There are 5 + 4 = 9 non - fiction books on the cart. There are 2 * 5 = 10 autobiographies on the cart. There are 5 + 9 + 10 = 24 fiction, non - fiction, and autobiography books on the cart. There are 35 - 24 = 11 picture books on the cart.
The answer: 11
What was the question?
Question: There are 35 books on the cart. There are five fiction books, 4 more non-fiction books than fiction books, 2 times as many autobiographies as fiction books, and the rest picture books. How many books were picture books?


The younger son received three times as many toys as the elder son, which is 3 * 60 = 180 toys. Since he bought the toys together, he purchased 180 + 60 = 240 toys.
The answer: 240
Reverse engineering the question: Mr. Desmond bought three times as many toys for his younger son as he bought for his elder son. If the elder son received 60 toys, how many toys did Mr Desmond buy?


If there are 600 boys at the event, and the difference between boys and girls is 400, there are 600 + 400 = 1000 girls. The total number of boys and girls at the event is 1000 + 600 = 1600. 60% of the total number of boys and girls at the event is 60 / 100 * 1600 = 960.
The answer: 960
Reverse engineering the question:
The difference between the number of boys and girls in a tree planting event is 400. If there are 600 boys at the event, and the number of girls is more than the number of boys, what's 60% of the total number of boys and girls at the event?
