There are 8 tiles along the width and 20 tiles along the height for a total of 8 * 20 = 160 tiles. Each wall has 160 tiles and there are 3 walls so there are 160 * 3 = 480 tiles in the shower.
The answer: 480
Reverse engineering the question: Each wall of a 3 sided shower has 8 tiles running the width of the wall and 20 tiles running the height of the wall. How many tiles are in the shower?
Reasoning and answer: Jamal started with B books in the cart. He had B - 12 books after the history section. He had B - 12 - 19 = B - 31 books after the fiction section. He had B - 31 - 8 + 4 = B - 35 books after the children's section. He still had B - 35 = 16 books to shelve. Thus, he started with B = 16 + 35 = 51 books in the cart.
The answer: 51
What was the question?
Question: Jamal works at a library shelving books. He has a cart full of books to put away in different sections. In the history section, he shelves 12 books. In the fiction section, he shelves 19 books. In the children's section, he shelves 8 books but finds 4 that were left in the wrong place that he adds to his cart to shelve elsewhere. He still has 16 books to shelve. How many books did he start with in the cart?
Kyro owes Fernanda half of what Aryan owes Fernanda, a total of 1 / 2 * $1200 = $600. Aryan pays 60% of her dept, which equals 60 / 100 * 1200 = $720. If Fernanda adds the amount she's been paid by Aryan to her savings account, it increases to $300 + $720 = $1020. Kyro also pays her debt by 80 / 100 * $600 = $480. When Fernanda adds the amount she's been paid by Kyro to her savings account, the total amount of money in the savings account increases to $1020 + $480 = $1500.
The answer: 1500
Reverse engineering the question: Aryan owes Fernanda $1200, which is twice what Kyro owes Fernanda. Aryan decides to pay 60% of her debt to Fernanda, and Kyro pays Fernanda 80% of her dept. If Fernanda had $300 in her savings account and adds the money she's been paid by her debtors to the savings account, calculate the total amount of money in her savings account now.
Reasoning and answer: There were 2 * 500 = 1000 people at the counting station who were counted on the first day. In the two days, 1000 + 500 = 1500 were counted at the station.
The answer: 1500
What was the question?
Question: At a people counting station, the number of people counted on the first day was twice the total number counted on the second day. If 500 people were counted on the second day, how many people were counted on the two days?
If the difference in scores between Farah and Hajar in the game is 21 points, and Hajar's score is 24, then Farah has a score of 21 + 24 = 45 points. The overall score in the game is 45 + 24 = 69.
The answer: 69
Reverse engineering the question: In a guessing game, Hajar's score is 24 points. The difference in the scores between Hajar and Farah's score in the game is 21. What is the sum of their scores, assuming Farah's score is higher than Hajar's?
The squirrel steals 1 / 2 cup of birdseed every week, so the birds eat 2 - 1 / 2 = 1 1 / 2 cups of birdseed. Each cup feeds 14 birds, so Ivan's bird feeder feeds 14 * 1 1 / 2 = 21 birds weekly.
The answer: 21
Reverse engineering the question:
Ivan has a bird feeder in his yard that holds two cups of birdseed. Every week, he has to refill the emptied feeder. Each cup of birdseed can feed fourteen birds, but Ivan is constantly chasing away a hungry squirrel that steals half a cup of birdseed from the feeder every week. How many birds does Ivan's bird feeder feed weekly?
