The program normally takes 3 + 5 = 8 years. So he manages to finish in 8 * 3 / 4 = 6 years.
The answer: 6
Reverse engineering the question: Tom goes to a combined undergrad and Ph.D. program. It takes 3 years to finish the BS and 5 years to finish the Ph.D. Tom finishes it in 3/4ths the time. How long does it take for him to finish?


Reasoning and answer: Two hours means 2 * 60 = 120 minutes. So in 2 hours, there are with 120 / 15 = 8 groups of 15 minutes. So on average Xavier can score 8 * 2 = 16 goals.
The answer: 16
What was the question?
Question: Xavier plays football with his friends. During 15 minutes Xavier can score 2 goals on average. How many goals on average is Xavier able to score, when the match lasted for 2 hours?


Let x be the amount spent on a shirt. Greg spent 2x + 9 dollars on shoes. 300 = x + (2x + 9). 300 = 3x + 9. 291 = 3x. x = 97$. Greg spent 97$ on a shirt.
The answer: 97
Reverse engineering the question: While shopping, Greg spent 300$ on a shirt and shoes. If Greg spent 9 more than twice as much on shoes as he did a shirt, how much did Greg spend on a shirt?


Reasoning and answer: A total of 12 x 10 = 120 bottles will be placed in 10 crates. Therefore, 130 - 120 = 10 bottles will not be placed in a crate.
The answer: 10
What was the question?
Question: Joshua packs 12 bottles in each crate. He has a total of 130 bottles and 10 crates. How many bottles will not be placed in a crate?


On Saturday, she sold 2 * 30 = 60 boxes. On Sunday, she sold 60 - 15 = 45 boxes. She sold a total of 30 + 60 + 45 = 135.

Reverse engineering the question: On Friday, Markeesha sold 30 boxes of crackers for her scout troop's fundraiser. On Saturday, she sold twice as many as on Friday. On Sunday, she sold 15 fewer than Saturday. How many boxes did she sell over the three days?


Let x represent the number of miles Kati drives. Michelle:3x. Tracy:20 + 2(3x) = 20 + 6x. Total:x + 3x + 20 + 6x = 1000. 10x + 20 = 1000. 10x = 980. x = 98 miles. 3(98) = 294 miles.
The answer: 294
Reverse engineering the question:
Tracy, Michelle, and Kati take a road trip that is a total of 1000 miles. Tracy drives 20 miles more than twice Michelle, and Michelle drives 3 times the amount that Katie drives. How many miles does Michelle drive?
