In the second month, Vinny lost half as much as he had the first month, so he lost 20 pounds / 2 = 10 pounds. In the third month, he again lost half as much which was 10 pounds / 2 = 5 pounds. And in the fourth month, he lost 5 pounds / 2 = 2.5 pounds. So in total, Vinny lost 20 + 10 + 5 + 2.5 = 37.5 pounds in the first four months. Over his entire diet, he had lost 300 – 250.5 = 49.5 pounds. So in the fifth month, Vinny must have lost 49.5 pounds total loss – 37.5 pounds loss in the first four months = 12 pounds.
The answer: 12
Reverse engineering the question: Vinny weighed 300 pounds then lost 20 pounds in the first month of his diet. He continued his diet but each month, he lost half as much weight as he had lost in the previous month. At the start of the fifth month of his diet, he worked harder to lose extra weight then decided to end his diet. If Vinny weighed 250.5 pounds at the end of his diet, how many pounds did he lose throughout the fifth month?


Reasoning and answer: The refurbished T - shirt costs $5 / 2 = $2.5. He earn $2.5 x 6 = $15 for the refurbished T - shirt. He can earn $5 x 2 = $10 for the T - shirts. He can earn $4 x 1 = $4 for the pants. He can earn $6 x 4 = $24 for the skirts. Therefore Karl can earn a total of $15 + $10 + $4 + $24 = $53.
The answer: 53
What was the question?
Question: Karl sells clothing in his store. He sells a T-shirt that costs $5, some pants that cost $4, and some skirts that cost $6, he also sells some refurbished t-shirts that cost half the original price. How much is his total income if he sold two T-shirts, one pair of pants, four skirts, and six refurbished T-shirts?


Lyra only paid $480 for the pair of shoes which is only 100% - 20% = 80% of the original price. So let x be the original price. Then 0.8x = $480. Thus x = $480 / 0.8 = $600.
The answer: 600
Reverse engineering the question: Lyra bought a pair of shoes at a 20% discount. If she paid $480, how much was the original price of the pair of shoes?


Reasoning and answer: Gordon has 4 / 2 = 2 Persians. Gordon has 2 + 1 = 3 Maine Coons. Hawkeye has 3 - 1 = 2 Maine Coons. In total, they have 4 + 2 + 2 + 3 + 2 + 0 = 13 cats.
The answer: 13
What was the question?
Question: Jamie owns 4 Persian cats and 2 Maine Coons. Gordon owns half as many Persians and one more Maine Coon than Jamie. Hawkeye owns one less Maine Coon than Gordon and no Persian cats. If they bring all of their cats together to play, how many cats are there in total?


A box of 12 bars was shared equally between 3 people so each person got 12 / 3 = 4 bars. Mike and Rita together got 4 + 4 = 8 bars.
The answer: 8
Reverse engineering the question: A box of chocolate bars was shared equally between Mike, Rita and Anita. If the box contains 12 bars, how many bars did Mike and Rita get (combined)?


Colton gave away 4 stickers * 3 friends = 12 stickers. Colton gave Mandy 2 + 12 stickers = 14 stickers. Colton gave Justin 14 stickers - 10 = 4 stickers. In total, Colton gave away 12 + 14 + 4 stickers = 30 stickers. Colton's number of total stickers at the end is 72 - 30 = 42 stickers.
The answer: 42
Reverse engineering the question:
Colton had 72 dolphin stickers. He gave 4 stickers each to 3 friends. He also gave his friend Mandy 2 more than he gave his three friends total.  And he gave Justin 10 less than Mandy. How many stickers does Colton have left?
