Question: Kaiden and Adriel were to pick a certain number of apples from their farm. After picking 400 apples each, they realized they still had to pick some more, so each picked 3/4 times as many as they had picked earlier. When they checked the pickup truck that was carrying the apples, they found out they still needed to pick 600 apples each to reach the target number. How many apples were they targeting to pick?
Answer: When they picked 400 apples each in the first round, they picked a total of 2 * 400 = 800 apples. They picked 3 / 4 * 400 = 300 apples each in the second round. The total number of apples they picked in the second round is 2 * 300 = 600. The total number of apples they'd picked so far is 800 + 600 = 1400. When they checked the pickup truck that was carrying the apples, they found out they still needed to pick 600 apples each to reach the target number, a total of 2 * 600 = 1200. The target number of apples they had to pick is 1200 + 1400 = 2600. The answer is 2600.
[Question]Mr. Desmond bought three times as many toys for his younger son as he bought for his elder son. If the elder son received 60 toys, how many toys did Mr Desmond buy?
[Answer]The younger son received three times as many toys as the elder son, which is 3 * 60 = 180 toys. Since he bought the toys together, he purchased 180 + 60 = 240 toys. The answer is 240.
Q: Don can paint 3 tiles a minute, Ken can paint 2 more tiles a minute than Don and Laura can paint twice as many tiles as Ken. Kim can paint 3 fewer tiles than Laura can in a minute. How many tiles can Don, Ken, Laura and Kim paint in 15 minutes?
A: Ken paints 3 tiles / minute + 2 tiles / minute = 5 tiles / minute. Laura can paint 5 tiles / minute x 2 = 10 tiles / minute. Kim can paint 10 tiles / minute - 3 tiles / minute = 7 tiles / minute. All 4 can paint 3 tiles / minute + 5 tiles / minute + 10 tiles / minute + 7 tiles / minute = 25 tiles / minute. In 15 minutes, they can paint 15 minutes x 25 tiles / minute = 375 tiles. The answer is 375.
Question: To make fried green tomatoes, Thelma cuts each green tomato into 8 slices before cooking them up. If 20 slices of fried green tomato make a meal for a single person, how many tomatoes will Thelma need to make enough fried green tomatoes to feed a family of 8 for a single meal?
Answer: If 20 slices are sufficient for a meal to feed a single person, then to feed eight Thelma will need 8 * 20 = 160 slices of tomato. At 8 slices per tomato, Thelma will need 160 / 8 = 20 tomatoes to feed a family of 8. The answer is 20.
