Q: 3/5 of the mangoes on a mango tree are ripe. If Lindsay eats 60% of the ripe mangoes, calculate the number of ripe mangoes remaining if there were 400 mangoes on the tree to start with.
A: The number of ripe mangoes from the tree is 3 / 5 * 400 = 240. If Lindsay eats 60% of the ripe mangoes, she eats 60 / 100 * 240 = 144 mangoes. The total number of ripe mangoes remaining is 240 - 144 = 96. The answer is 96.
Question: Betty is 60 years old, and she is the oldest person in the family. Her daughter is 40 percent younger than she is, and her granddaughter is one-third her mother's age. How old is the granddaughter?
Answer: Betty's daughter is 40 / 100 * 60 = 24 years younger than she is. That means her daughter is 60 - 24 = 36 years old. So the granddaughter is 1 / 3 * 36 = 12 years old. The answer is 12.
[Question]Tom needs to lower a rope down 6 stories.  One story is 10 feet. The only rope being sold is 20 feet long but you lose 25% when lashing them together. How many pieces of rope will he need to buy?
[Answer]He needs 10 * 6 = 60 feet. He loses 20 * .25 = 5 feet each time. So he gets 20 - 5 = 15 feet from each piece. That means he needs 60 / 15 = 4 pieces of rope. The answer is 4.
Q: Charles can earn $15 per hour when he housesits and $22 per hour when he walks a dog. If he housesits for 10 hours and walks 3 dogs, how many dollars will Charles earn?

Question: Wendi brought home 4 chickens. After a few days, she brought home enough additional chickens to double the number of chickens she owned. Then, a neighbor's dog ate one of her chickens. Finally, Wendi found an additional 4 less than ten chickens and brought them home too. After this, how many chickens does Wendi have?
Answer: Wendi doubled her number of chickens from 4 to 4 * 2 = 8 chickens. After a dog ate one of the chickens, 8 - 1 = 7 chickens remained. 4 less than 10 is 10 - 4 = 6. Therefore, Wendi added another 4 less than ten chickens for a total of 7 + 6 = 13 chickens. The answer is 13.
Q: In a spelling contest held in her school, Drew got 20 questions correct, winning her the competition. She got six questions wrong, and her competitor Carla got 14 questions correct, and twice as many questions wrong as the number of questions Drew got wrong. If each competitor was asked a different question, how many questions were asked in the competition?
A:
Since Drew got 20 questions right and 6 wrong, she was asked 20 + 6 = 26 questions. Carla got twice as many questions wrong as Drew got, a total of 2 * 6 = 12 questions wrong. The total number of questions that Carla was asked is 12 + 14 = 26. Altogether, there were 26 + 26 = 52 questions that were asked in the contest. The answer is 52.
