The number of seats sold was 0.75 * 60,000 = 45,000. And 45,000 - 5,000 = 40,000.
The answer: 40000
Reverse engineering the question: The stadium seats 60,000 fans, but only 75% of the seats were sold for the music show. Because of the threat of rain, 5,000 fans stayed home. How many attended the show?
Reasoning and answer: Harry's father is 50 years + 24 years = 74 years old. Harry's mother is 1 / 25 * 50 years = 2 years younger than his father. So she is currently 74 years - 2 years = 72 years old. So when Harry was born, she was 72 years - 50 years = 22 years old.
The answer: 22
What was the question?
Question: Harry is 50 years old. His father is currently 24 years older than he is. How old was his mother when she gave birth to him if she is younger than his father by 1/25 of Harry's current age?
If 1 bag has 20 cookies and a box has 4 bags, then in total there are 20 * 4 = 80 cookies inside the box. If 1 cookie has 20 calories and there are 80 cookies in the box, then the box has in total 20 * 80 = 1600 calories.
The answer: 1600
Reverse engineering the question: A bag of caramel cookies has 20 cookies inside and a box of cookies has 4 bags in total. How many calories are inside the box if each cookie is 20 calories?
Reasoning and answer: For the distance she traveled, Elise paid 23 - 3 = 20 dollars. Since the cost per mile is $4, the distance from Elise's house to the hospital is 20 / 4 = 5 miles.
The answer: 5
What was the question?
Question: Very early this morning, Elise left home in a cab headed for the hospital. Fortunately, the roads were clear, and the cab company only charged her a base price of $3, and $4 for every mile she traveled. If Elise paid a total of $23, how far is the hospital from her house?
The vans held 9 vans * 8 people = 72 people. The buses held 10 buses * 27 people = 270 people. The total number of people on the field trip is 72 + 270 = 342 people.
The answer: 342
Reverse engineering the question: A group of science students went on a field trip. They took 9 vans and 10 buses. There were 8 people in each van and 27 people on each bus. How many people went on the field trip?
Let x be the number of feet in John's pool. 2 * x + 5 = 15. 2x = 10. x = 5.
The answer: 5
Reverse engineering the question:
John's pool is 5 feet deeper than 2 times Sarah's pool. If John's pool is 15 feet deep, how deep is Sarah's pool?
