Two weeks has 5 * 2 = 10 weekdays. Two weeks has 2 * 2 = 4 weekends. On weekdays, she reads 10 * 10 = 100 pages in total. On weekends, she reads 20 * 4 = 80 pages in total. So the book has 100 + 80 = 180 pages.
The answer: 180
Reverse engineering the question: Sally reads 10 pages of a book on weekdays and 20 pages on weekends. If it takes 2 weeks for Sally to finish her book, how many pages that book has?


Reasoning and answer: They earned 8 * 2 = $16 from the small pizzas. The large pizzas earned 40 - 16 = $24. They sold 24 / 8 = 3 large Pizzas.
The answer: 3
What was the question?
Question: The pizzeria sells small pizzas for $2 and large pizzas for $8. They sold $40 in pizzas. If they sold 8 small pizzas, how many large pizzas did they sell?


Ed spent $1.50 x 6 = $9 for staying in the hotel last night. He spent $2 x 4 = $8 for staying in the hotel this morning. So, the total money he spent in the hotel is $9 + $8 = $17. Therefore, he still has $80 - $17 = $63 left after staying in the hotel.
The answer: 63
Reverse engineering the question: Ed booked a hotel while he was on vacation. Staying at the hotel cost was $1.50 per hour every night and $2 per hour every morning. If Ed had $80 and he stayed in the hotel for 6 hours last night and 4 hours this morning, how much money was he left with after paying for his stay at the hotel?


Reasoning and answer: The desk price was raised 65 - 15 = $50. At $5 per bid, there were 50 / 5 = 10 bids on the desk. There were two bidders, so each bid 10 / 2 = 5 times on the desk.
The answer: 5
What was the question?
Question: An auctioneer raises the price of an item he is auctioning by $5 every time someone new bids on it. Two people enter a bidding war on a desk and the price goes from $15 to $65 before the desk is sold. How many times did each person bid on the desk?


If Mary weighs 160 lbs, Jamison weighs 160 lbs + 20 lbs = 180 lbs. If John weighs one - quarter less than what Mary weighs, he weighs 1 / 4 * 160 lbs = 40 lbs more. The total weight of John is 160 lbs + 40 lbs = 200 lbs. The total weight for the three is 200 lbs + 180 lbs + 160 lbs = 540 lbs.
The answer: 540
Reverse engineering the question: John weighs one-quarter times more than what Mary weighs. Mary weighs 20 lbs less than Jamison's weight. If Mary weighs 160 lbs, what's the combined weight of the three?


There are 74 - 14 = 60 apples left after Ricki removes some. Samson removes 14 * 2 = 28 apples. There are 60 - 28 = 32 apples left after Samson removes some.
The answer: 32
Reverse engineering the question:
At the beginning of the day there were 74 apples in a basket. If Ricki removes 14 apples and Samson removes twice as many as Ricki. How many apples are left in the basket by the end of the day?
