Question: Miles is going to spend 1/6 of a day reading. He will read comic books, graphic novels, and novels. He reads 21 pages an hour when he reads novels, 30 pages an hour when he reads graphic novels, and 45 pages an hour when he reads comic books. If he reads each for 1/3 of his time, how many pages does he read?
Answer: Miles will read for 4 hours because 24 x (1 / 6) = 4. He will read each type for 1 and 1 / 3 hours because 4 / 3 = 1 and 1 / 3. He will read 28 pages of novels because 21 x (1 and 1 / 3) = 28. He will read 40 pages of graphic novels because 30 x (1 and 1 / 3) = 40. He will read 60 pages of comic books because 45 x (1 and 1 / 3) = 60. He will read 128 pages in total because 28 + 40 + 60 = 128. The answer is 128.

Question: A hot air balloon with 200 balloons is blowing up. After about half an hour, 1/5 of the total number of balloons in the hot air balloon have blown up. After another hour, twice the number of balloons that had already blown up also blow up. How many balloons in the hot air balloon remain intact?
Answer: After half an hour, the number of balloons that had blown up is 1 / 5 * 200 = 40. The number of balloons that haven't blown up so far is 200 - 40 = 160. In the next hour, 2 * 40 = 80 balloons blow up. The number of balloons that haven't blown up now is 160 - 80 = 80. The answer is 80.

Question: How many apples did two men and three women buy at a certain store if the two men each bought 30 apples, 20 less than the number of apples bought by each woman?
Answer: If the two men each bought 30 apples, together they bought 2 * 30 = 60 apples. Since the two men each bought 30 apples, 20 less than the total number of apples bought by each woman, each woman bought 20 + 30 = 50 apples. The total number of apples bought by the women is 3 * 50 = 150. Altogether, the two men and three women bought 60 + 150 = 210 apples. The answer is 210.

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.
