On Monday the total number of miles Alice walks to and from school is 10 + 12 = 22 miles. For the other 4 days, from Tuesday to Friday, she walks an additional 4 * 22 = 88 miles. The total number of miles she will have walked by Friday 22 + 88 = 110 miles.
The answer: 110
Reverse engineering the question: Every Monday to Friday morning, Alice walks 10 miles through a large grass field to get to school. To avoid the hot afternoon sun on her way home, she walks 12 miles through a forest. When she gets home on Friday, how many miles will she have walked that week?


Reasoning and answer: In the second week, 15 x 3 = 45 bags of chips were sold. So there was a total of 45 + 15 = 60 bags of chips sold on the first and second week. Thus, a total of 100 - 60 = 40 bags of chips were sold on the third and fourth week. Therefore, 40 / 2 = 20 bags of chips were each sold on the third and fourth week.
The answer: 20
What was the question?
Question: A convenience store sold 100 bags of chips in a month. In the first week, 15 bags of chips were sold. In the second week, thrice as many bags of chips were sold. There was an equal number of chips sold in the third and fourth week. How many chips was each sold in the third and fourth week?


Samuel bought 20 + 8 = 28 apples. Samuel ate 28 / 2 = 14 apples. Samuel used 28 / 7 = 4 to make apple pie. Samuel has 28 - 14 - 4 = 10 apples left.
The answer: 10
Reverse engineering the question: Bonnie and Samuel went to the market together. Bonnie bought 8 apples. Samuel bought 20 more apples than Bonnie. Samuel then ate half of them and used 1/7 of them to make apple pie. How many apples does Samuel have left?


Reasoning and answer: If the 12 students had shared the 108 oranges, each student would have gotten 108 / 12 = 9 oranges. But 36 were removed so there are 108 - 36 = 72 oranges left. So 12 shared 72 for each to get 72 / 12 = 6 oranges. This is 9 - 6 = 3 less than they would each get if they did not have to throw any orange away.
The answer: 3
What was the question?
Question: A class of 12 students was about to share 108 oranges equally among themselves when it was discovered that 36 of the oranges were bad and had to be thrown away. How many oranges less will each student get now than if no orange had to be thrown away?


Kenny ran for 10 * 2 = 20 hours. Kenny practiced the trumpet for 20 * 2 = 40 hours.
The answer: 40
Reverse engineering the question: Kenny played 10 hours of basketball last week. He ran for twice as long as he played basketball, and he practiced on the trumpet for twice as long as he ran. How many hours did Kenny practice on the trumpet last week?


The amount of money deducted from Adam's daily pay is $40 / 10 = $4. So after deducting 10%, Adam’s daily pay is $40 – $4 = $36. This means that in 30 days he earns $36 * 30 = $1080.
The answer: 1080
Reverse engineering the question:
Adam earns $40 daily in his job. 10% of his money is deducted as taxes. How much money will Adam have earned after taxes after 30 days of work?
