Question: A group of security guards were hired for the night shift at a factory. The four guards agreed to a rotating schedule to cover the nine hours of the night shift. The first guard would take three hours since they were still awake, the last guard would wake up early and take two hours, and the middle two guards would split the remaining hours. How many hours will each middle guard take?
Answer: The first and last guard will take 3 + 2 = 5 hours of the night shift. There are 9 hours in the night shift, so the middle two guards will cover 9 - 5 = 4 hours. Each middle guard will take 4 / 2 = 2 hours. The answer is 2.
[Question]A group of nine turtles sat on a log. Two less than three times the original number of turtles climbed onto the log with the original group, creating an even larger group on the log. Suddenly, half of the large group of turtles were frightened by a sound and jumped off of the log and ran away. How many turtles remained on the log?
[Answer]Two less than three times the original number of turtles is (9 * 3) - 2 = 25. Thus, The original 9 were joined by 25 more, for a total of 25 + 9 = 34 turtles. But half of the 34 turtles scurried away, leaving half remaining, or 34 / 2 = 17 brave turtles. The answer is 17.
Q: One hundred people attended a party. Fifty percent of the attendees are women, thirty-five percent of them are men, and the rest are children. How many children attended the party?
A: Out of 100 attendees, 100 x 50 / 100 = 50 are women. While 100 x 35 / 100 = 35 are men. So there were a total of 50 + 35 = 85 men and women who attended the party. Thus, 100 - 85 = 15 children attended the party. The answer is 15.
Question: Sidney has 4 kittens and 3 adult cats. She has 7 cans of cat food. Each adult cat eats 1 can of food per day. Each kitten eats 3/4 of a can per day. How many additional cans of food does Sidney need to buy to feed all of her animals for 7 days.
Answer: Sidney has 3 adult cats * 1 can of food = 3 cans of food per day. Sidney's adult cats will need 3 cans * 7 days = 21 cans for the week. Sidney has 4 kittens * 3 / 4 cup of food = 3 cans of food per day. Sidney's kittens will need 3 cans * 7 days = 21 cans for the week. Sidney will need to buy 21 cans + 21 cans - 7 cans = 35 cans. The answer is 35.
