He bought 2 * 50 = 100 pages. It cost 5 * 100 = 500 cents. So he spent 500 / 100 = 5 cents per page.
The answer: 5
Reverse engineering the question: James buys 2 notebooks with 50 pages each. He pays $5. How many cents did each page cost?


Reasoning and answer: The first week he spends: $12 * 1 / 3 = $4. So he has $12 - $4 = $8 left. In the second week, he spends $8 x 1 / 4 = $2. So Tom has $8 - $2 = $6 left to finish the month.
The answer: 6
What was the question?
Question: Tom receives a $12 allowance per month. In the first week, he spends a third of it; in the second week, he spends a quarter of what he has left. How much money does he have left to finish the month?


At a rate of 30 minutes per poodle, 3 poodles will take 3 * 30 = 90 minutes. If it takes half as much time to groom a terrier as it takes to groom a poodle, it takes 30 / 2 = 15 minutes per terrier. At a rate of 15 minutes per terrier, 8 terriers will take 120 minutes. Thus, in total, it will take the pet shop 90 + 120 = 210 minutes to groom 3 poodles and 8 terriers.
The answer: 210
Reverse engineering the question: The pet shop grooms dogs. It takes 30 minutes to groom a poodle. It takes half as much time to groom a terrier as it takes to groom a poodle. They do not groom cats. If the pet shop grooms 3 poodles and 8 terriers, what is the total length of time it will take, in minutes?


Reasoning and answer: Georgia's test started with 75 problems and then Georgia completed 10, 75 - 10 = 65 problems. After 20 minutes she completes twice as many problems, 10 x 2 = 20. With 40 minutes left she has completed 10 + 20 problems = 30 problems. From the original 75 problems she has solved 30, 75 - 30 = 45 problems she has left.
The answer: 45
What was the question?
Question: Georgia is working on a math test with 75 problems on it. After 20 minutes she has completed 10 problems. After another 20 minutes, she has completed twice as many problems. She has 40 minutes to complete the rest of the test. How many problems does she have left to solve?


The supermarket has 15 cases × 24 tins / case = 360 tins of beans delivered to them. There are 360 tins × 0.05 = 18 tins that are damaged and unsellable. So in the end, there are 360 tins - 18 tins = 342 tins of beans that are left.
The answer: 342
Reverse engineering the question: A supermarket receives a delivery of 15 cases of tins of beans. Each case contains 24 tins. If 5% of the tins are damaged and thrown away, how many tins of beans are left?


The clay pot costs $20 + $9 = $29. The bag of soil costs $9 - $2 = $7. The cost to plant the flowers is $9 + $29 + $7 = $45.
The answer: 45
Reverse engineering the question:
The flowers cost $9, the clay pot costs $20 more than the flower, and the bag of soil costs $2 less than the flower. How much does it cost to plant the flowers?
