Question: Barry stands on his head for 10 minutes at a time, but then he must sit for 5 minutes before he can take another turn standing on his head. How many turns can Barry take standing on his head during a single 2-hour period?
Answer: Each turn Barry takes standing on his head lasts for 10 + 5 = 15 minutes. 2 hours is 60 * 2 = 120 minutes. Barry can take 120 / 15 = 8 turns standing on his head over two hours. The answer is 8.
[Question]Barry, Thomas and Emmanuel are to share a jar of 200 jelly beans. If Thomas takes 10%, and Barry and Emmanuel are to share the remainder in the ratio 4:5 respectively, how many jelly beans will Emmanuel get?
[Answer]10% of 200 jelly beans is (10 / 100) * 200 = 20 jelly beans. Thomas takes 20 jelly beans leaving 200 - 20 = 180 jelly beans. 180 jelly beans are to be shared in the ratio 4:5 so each share is 180 / (4 + 5) = 20 jelly beans. Emmanuel gets 5 shares which is 5 * 20 = 100. The answer is 100.
Q: Tina buys a loaf of bread for $50, 2oz of ham for $150, and a cake for $200. What percent of the cost is the ham and bread?
A: The total cost of buying bread and ham was $50 + $150 = $200. Together with the cake, Tina paid $200 + $200 = $400 for the items. Since the total percentage for all the items is 100%, the cost of ham and bread is $200 / $400 * 100% = 50% of the total cost of items. The answer is 50.
