To move in, Janet had to pay 2 months worth of rent so that would cost 2 * 1250 = $2,500. On top of the rent she needed to pay a deposit of $500 so 2500 + 500 = $3,000 total to rent the apartment. If it cost $3000 to move in and she had $2225 then she need 3000 - 2225 = $775 more.
The answer: 775
Reverse engineering the question: Janet wanted to move out of her parents' house and rent her own apartment. She had $2,225 saved. She found an apartment that cost $1,250 per month that was perfect for her. The landlord said that she needed to be able to pay 2 months' rent in advance to rent the place and she would also need to put down a deposit of $500. How much more money did Janet need in order to rent the apartment?


Reasoning and answer: Patrick eats 1 / 2 of the 4 egg rolls that Alvin eats, 1 / 2 x 4 = 2 egg rolls. Matthew eats 3x as many egg rolls as Patrick eats, 3 x 2 = 6 egg rolls that Matthew eats.
The answer: 6
What was the question?
Question: Matthew, Patrick and Alvin are eating dinner together. Matthew eats three times as many egg rolls as Patrick eats. Patrick eats half as many egg rolls as Alvin eats. If Alvin ate 4 egg rolls, how many did Matthew eat?


In the morning he travels at an average speed of 30mph for 1 hour so he covers a distance of 30 * 1 = 30 miles. He covers the same distance of 30 miles in the evening spending 1.5 hours so his average speed must be 30 / 1.5 = 20mph.
The answer: 20
Reverse engineering the question: Mr. Maxwell takes 1 hr to drive to work in the morning but 1 and half hours to drive back home in the evening. If the morning and evening traffic is similar and he drives at an average speed of 30mph in the morning, what is the average speed of his return journey?


Reasoning and answer: Amy's score was 2 + 4 = 6. Jason's score was 6 x 2 = 12. So, their team's score was 2 + 6 + 12 = 20.
The answer: 20
What was the question?
Question: Connor scored 2 in a game while Amy scored 4 more than Connor. Jason scored twice the score of Amy. If Connor, Amy, and Jason belong to the same team, how many points did their team have?


Let x be the number of years Tom has been teaching. Devin has been teaching for (1 / 2)x - 5 years. 70 = x + ((1 / 2)x - 5). 70 = (3 / 2)x - 5. 75 = (3 / 2)x. x = 50. Tom has been teaching for 50 years.
The answer: 50
Reverse engineering the question: Tom and Devin have been teaching for a total of 70 years. Devin has been teaching for 5 less than half the number of years that Tom has. How many years has Tom been teaching?


There are twice as many frogs as dogs in the compound, meaning there are 160 / 2 = 80 dogs. The total number of frogs and dogs in the compound is 80 + 160 = 240. The number of cats is less than 20% of the number of dogs, which means there are 20 / 100 * 80 = 16 dogs more than the number of cats. Therefore, the number of cats is 80 - 16 = 64 cats. The total number of animals in the compound is 64 cats + 240 dogs and frogs = 304 animals.
The answer: 304
Reverse engineering the question:
In a compound, the number of cats is 20% less than the number of dogs. There are also twice as many frogs as the number of dogs in the compound. Calculate the total number of animals present in the compound if there are 160 frogs.
