If there are 600 people at the fair this year, the number going to the fair next year is 2 * 600 = 1200. The number of people at the fair this year and the ones going next year totals 1200 + 600 = 1800. The number of people who went to that fair last year was 200 less than those going next year, meaning there were 1200 - 200 = 1000 people at the fair last year. In the three years, the number of people at the fair will be 1800 of this and next year + 1000 of last year = 2800.
The answer: 2800
Reverse engineering the question: Next year, there will be twice as many people going to the fair as are going this year, and the number of people who went to the fair last year was 200 less than those going next year. If the number of people going to the fair this year is 600, calculate the number of people at the fair in the three years.


Reasoning and answer: Sunday’s class is half the size of Saturday’s class with 20 kids so Sunday has 20 / 2 = 10 kids. She has 20 kids on Saturday and 10 kids on Sunday for a total of 20 + 10 = 30 kids. She charges $10.00 per kid and teaches 30 kids over the weekend so she makes 10 * 30 = $300.00.
The answer: 300

Question: Claudia offers art classes to kids and charges $10.00 for her one-hour class. If 20 kids attend Saturday’s class and half that many attend Sunday’s class, how much money does she make?


Half his friends are boys because 1 - 1 / 2 = 1 / 2. He plays with four boys because 8 x 1 / 2 = 4.
The answer: 4
Reverse engineering the question: Ocho has 8 friends and half are girls. His friends who are boys like to play theater with him. How many boys play theater with him?


Reasoning and answer: Jerry took 2 * 8 = 24 hours fixing the broken kitchen counter. Together, painting the house and fixing the broken kitchen counter took him 24 + 8 = 32 hours. If he also took 6 hours mowing the lawn, the total time he spent working for Miss Stevie is 32 + 6 = 38. Since he charged $15 per hour of work, he was paid 38 * $15 = $570.
The answer: 570
What was the question?
Question: Jerry was contracted to work on a house by his neighbor Miss Stevie. The time it took him to fix the broken kitchen counter was three times longer than the time he took painting the house. He took 8 hours painting the house and then helped mow Miss Stevie's lawn, taking 6 hours. If he charged Miss Stevie $15 per hour of work, calculate the amount of money that Miss Stevie paid him.


She either won or lost 60 games because 100 - 40 = 60. We know that 1(60 - Losses) - 2(Losses) =  - 30 because she lost $30. Therefore 60 - Losses - 2 Losses =  - 30. Therefore - 3 Losses =  - 90. Therefore, Losses = 30.
The answer: 30
Reverse engineering the question: Sarah is playing tic-tac-toe. She wins $1 for every game she wins, $0 for every game she ties, and she loses $2 for every game she loses. If she played 100 games where she tied 40 of them, and she lost $30, how many games did she win?


Mary carried 4 + 3 = 7 buckets of sand. Iris carried 7 – 1 = 6 buckets of sand. All together, they carried 4 + 7 + 6 = 17 buckets of sand. The sand weighed a total of 17 * 2 = 34 pounds.
The answer: 34
Reverse engineering the question:
Eden, Mary and Iris gather sand to fill their sandbox. Eden carried 4 buckets of sand. Mary carried 3 more buckets of sand than Eden. Iris carried 1 less bucket of sand than Mary. If each bucket contains 2 pounds of sand, how many pounds of sand did they collect in total?
