Each student got 62 + 43 = 105 pens to start with. They pooled them to get 105 * 3 = 315 pens in the pool. They took 37 pens in the first month, leaving 315 - 37 = 278 pens in the pool. They took 41 pens in the second month, leaving 278 - 41 = 237 pens in the pool. 237 pens were split into three equal parts to give 237 / 3 = 79 pens each.
The answer: 79
Reverse engineering the question: Jane bought pens for her three students. Each student received 62 red pens and 43 black pens. They pooled their pens together and took them from the pool whenever they needed them. After the first month, they had taken a total of 37 pens from the pool. After the second month, they had taken another 41 pens from the pool. Then Jane decided to split the remaining pens equally among them. How many pens will each student get now?

He gave 2 * 20 = $40. So the total cost was 40 - 16 = $24. That means each slice costs 24 / 3 = $8. That means it costs 8 * 100 = 800 cents. So each slice is 800 / 20 = 40 cents.
The answer: 40
Reverse engineering the question: Tim buys 3 loaves of bread. Each loaf of bread has 20 slices. He pays for the 3 loaves of bread with 2 $20 bills. He gets $16 change. How much does each slice cost, in cents?

55 miles north and 95 miles west give 55 + 95 = 150 miles total. 150 miles at 25 miles an hour gives 150 / 25 = 6 hours.
The answer: 6
Reverse engineering the question: Tod drives his family car 55 miles to the north and 95 miles to the west. If Tod constantly drives 25 miles an hour the entire trip how many hours did Tod drive?

On Monday, there were 50 visitors. On Tuesday, there were twice as many, so 2 * 50 = 100 visitors. The total number of visitors after Tuesday will be 100 + 50 = 150 visitors. For the remaining 5 days, an average of 20 visitors attended, giving a total of 5 * 20 = 100 visitors. The total number of visitors who visited the library for the week was 100 + 150 = 250 visitors.
The answer: 250
Reverse engineering the question:
Jenny's local library received 50 visitors on Monday. On Tuesday, the library received twice that number. On the remaining days of the week, an average of 20 visitors went to the library. What's the total number of visitors who went to the library that week?
