The wide cupboard holds twice as many glasses as the tall cupboard, amounting to 20 * 2 = 40 glasses. Each of the shelves in the narrow cupboard holds 15 / 3 = 5 glasses. Since a shelf was broken, a narrow cupboard now holds only 15 – 5 = 10 glasses. In total, there are 20 + 40 + 10 = 70 glasses.
The answer: 70
Reverse engineering the question: Damien collects glasses for a hobby and decides he wants to put them in display cupboards. His tall cupboard can hold 20 glasses, his wide cupboard can hold twice as many, and his narrow cupboard can hold 15 glasses with the glasses divided equally among the three shelves. As Damien is putting glasses in the narrow cupboard, he accidentally breaks one of the shelves. If all of the cupboards are full, how many glasses are currently being displayed?


Reasoning and answer: Let's let "x" be the original number of dolls in Lucy's doll collection. Then, 2 dolls equals an increase of 25%, and this can be written as x * 0.25 = 2. Solving for x we get x = 2 / 0.25 = 8 dolls in Lucy's original collection. After the gift of two new dolls, Lucy's collection contains 8 + 2 = 10 dolls.
The answer: 10

Question: Ethyl bought Lucy two new dolls for her doll collection. This increased the doll collection by 25%. After the addition of the two new dolls, how many dolls are in Lucy's collection?


The drinks cost a total of $4 per drink * 2 drinks = $8. So the sandwiches cost a total of $26 total spending - $8 spending on drinks = $18. Therefore, each sandwich costs $18 for sandwiches / 3 sandwiches = $6.
The answer: 6
Reverse engineering the question: Wade has called into a rest stop and decides to get food for the road. He buys a sandwich to eat now, one for the road, and one for in the evening. He also buys 2 drinks. If the drinks cost $4 each and Wade spends a total of $26 then how much, in dollars, did the sandwiches each cost?


Reasoning and answer: If 10 sales professionals each sell 10 cars per month, then they sell a combined 10 * 10 = 100 cars per month. If the store has 500 cars, then it will take the sales team 500 / 100 = 5 months to sell all of the cars.
The answer: 5

Question: At the Sterling Auto Store, they have 500 cars for sale. If they have 10 sales professionals, and each salesperson sells 10 cars per month, how many months will it take for them to sell all of the cars?


There are 9000 / (2 + 1) = 3000 hens on the farm. There are 3000 * 2 = 6000 roosters on the farm.
The answer: 6000
Reverse engineering the question: There are chickens roaming the chicken farm. The roosters outnumber the hens 2 to 1. If there are 9,000 chickens on the chicken farm, how many roosters are there?


Jess needs to walk 11 blocks + 6 blocks + 8 blocks = 25 blocks total. Jess needs to go 25 blocks – 5 = 20 blocks to get to work.
The answer: 20
Reverse engineering the question:
Before getting to work, Jess has a few errands to run. Jess has to walk 11 blocks to the store and 6 blocks to the gallery, before walking the final 8 blocks to arrive at work. If Jess has already walked 5 blocks, how many more blocks must she walk before arriving at work?
