[Question]Jennifer has ten pears, 20 oranges, and twice as many apples as pears. If she gives her sister two of each fruit, how many fruits does she have left?
[Answer]Jennifer has 2 * 10 = 20 apples. She has a total of 10 + 20 + 20 = 50 fruits. She gives her sister 2 pears + 2 oranges + 2 apples = 6 fruits. After giving her sister 2 of each fruit, she has 50 - 6 = 44 fruits left. The answer is 44.

[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.
[Answer]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 is 304.

[Question]One barnyard owl makes 5 hoot sounds per minute. If 5 less than 20 hoots per minute are heard coming out of the barn, how many Barnyard owls would this noise be coming from?
[Answer]5 less than 20 hoots per minute is 20 - 5 = 15 hoots per minute. If one barnyard owl makes 5 hoot sounds per minute, then 15 hoots per minute are coming from 15 / 5 = 3 barnyard owls. The answer is 3.

[Question]Aisha enjoys listening to music on her mp3 player. She starts with 500 songs on her mp3 player, then adds another 500 the week after that. She realizes her mp3 player has a large capacity for storing songs so she adds twice the amount she already had on her mp3 player. After a while, though, she decides that she doesn't like 50 of the songs and removes them. How many songs are on Aisha's mp3 player now?
[Answer]
Aisha starts with 500 songs + 500 songs = 1000 songs added to her mp3 player in the first two weeks. After that Aisha adds twice that amount to her mp3 player, 1000 x 2 = 2000 songs added. She now has 1000 + 2000 = 3000 songs on her mp3 player. However, she decides she wants to remove 50 of them, 3000 - 50 = 2950 songs on her mp3 player. The answer is 2950.
