A baker has a total of 10 + 15 = 25 cheesecakes both from the display and the fridge. Therefore, there are 25 - 7 = 18 more cheesecakes to be sold.
The answer: 18
Reverse engineering the question: A baker has 10 cheesecakes on the display while 15 more are still in the fridge. If the baker has sold 7 cheesecakes from the display, how many more cheesecakes are left to be sold?


Reasoning and answer: Marcy is bringing 6 tubs of lip gloss * 2 tubes of lip gloss per tub of lip gloss = 12 tubes of lip gloss. So she must be applying makeup to 12 tubes of lip gloss * 3 people per tube of lip gloss = 36 people.
The answer: 36
What was the question?
Question: Marcy is a makeup artist and has agreed to do some makeup for her friend's wedding. The only makeup she has limited stock of is lip gloss so she counts how many tubes she needs. Each tube of lip gloss will hold enough lip gloss for 3 people's makeup. Marcy decides to bring 6 tubs of lip gloss, each of which holds 2 tubes of lip gloss, and this will be the exact amount she needs for everyone's makeup. How many people is Marcy painting with makeup?


A triangle with a height of 2 inches and width of 2 inches has an area of 2 square inches because (1 / 2) x 2 x 2 = 2. The square has an area of 4 square inches because 2 x 2 = 4. 2 triangles would fit because 4 / 2 = 2.
The answer: 2
Reverse engineering the question: How many right triangles with a height of 2 inches and a width of two inches could fit inside a square with 2-inch sides?


Reasoning and answer: Madeline's essay was 150 x 2 = 300 words. Timothy's essay was 300 + 30 = 330 words. All together, they wrote 150 + 300 + 330 = 780 words. Their essays fill 780 / 260 = 3 pages.
The answer: 3
What was the question?
Question: Johnny wrote an essay with 150 words. Madeline wrote an essay that was double in length, and Timothy wrote an essay that had 30 words more than Madeline's. If one page contains 260 words, how many pages do Johnny, Madeline, and Timothy's essays fill?


Let x be the original price of the car. Then 40% * x = $15000. Thus x = $15000 / 0.4 = $37500.
The answer: 37500
Reverse engineering the question: Venny spent $15000 on a used car which cost 40% of the original price. What was the original price of the car?


She gets 1000 / 25 = 40 sections. She gives away 40 / 4 = 10 sections. So she keeps 40 - 10 = 30 sections. She keeps 30 / 2 = 15 sections on hand.
The answer: 15
Reverse engineering the question:
