Reasoning and answer: The long CD is 1.5 * 2 = 3 hours. The two shorter CDs have a combined length of 1.5 * 2 = 3 hours. So in total the CDs had a length of 3 + 3 = 6 hours.
The answer: 6

Question: James buys 3 CDs. Two of them are 1.5 hours each. The last one is twice that long. What is the combined length of the CDs?


Wendy drove 125 miles + 223 miles = 348 miles on the first two days. So on the third day, she drove 493 miles - 348 miles = 145 miles.
The answer: 145
Reverse engineering the question: On a three-day trip, Wendy drove 125 miles on the first day, and 223 miles on the second day. How many miles did she drive on the third day, if the total miles that Wendy drove for the trip is 493 miles?


Reasoning and answer: There are 16 ounces in one pound, and thus in 10 pounds of meat mix there are 10 * 16 = 160 ounces of sausage meat. Thus, the 40 sausage links contained 160 ounces of meat, or 160 / 40 = 4 ounces per link. If Brandy ate 12 links, then 40 - 12 = 28 links remained. Thus, 28 remaining links, at 4 ounces per link, contained 28 * 4 = 112 ounces of meat.
The answer: 112

The two Goldfish eat a total of 2 * 1 = 2 teaspoons of food. The 3 Swordtails eat a total of 3 * 2 = 6 teaspoons of food. The 8 Guppies eat a total of 8 * 1 / 2 = 4 teaspoons of food. In total, all of her fish eat 2 + 6 + 4 = 12 teaspoons of fish food.
The answer: 12
Reverse engineering the question: Layla is feeding her pet fish. She has two Goldfish which each get one teaspoon of fish food. Her 3 Swordtails each get 2 teaspoons of food. Her 8 Guppies each eat half a teaspoon of food. How much food does she have to give to her fish in total?


Reasoning and answer: In 2010 Timothy watched 24 + 7 = 31 movies. In 2010 Theresa watched 31 * 2 = 62 movies. In 2009 Theresa watched 24 / 2 = 12 movies. In both 2009 and 2010 Timothy and Theresa watched 24 + 31 + 62 + 12 = 129 movies.
The answer: 129
What was the question?
Question: Timothy and Theresa go to the movies very often. Timothy went to the movies 7 more times in 2010 that he did in 2009. In 2009, Timothy went to the movies 24 times. In 2010 Theresa went to see twice as many movies as Timothy did, but in 2009, she only saw half as many as he did. How many movies did Timothy and Theresa go on in both 2009 and 2010?


Reasoning and answer: If Bom has 300 seeds, then Gwi has 300 + 40 = 340 watermelon seeds. Together, Bom and Gwi have 340 + 300 = 640 melon seeds. Yeon's number of watermelon seeds is three times as many as the number that Gwi has, meaning Yeon has 3 * 340 = 1020 watermelon seeds. Together, the three friends have 1020 + 640 = 1660 watermelon seeds.
The answer: 1660
What was the question?
Question:
Yeon has three times as many watermelon seeds as Gwi. Gwi has 40 more watermelon seeds than Bom. If Bom has 300 watermelon seeds, how many seeds do they have together?
