[Question]In his company, Kenzo has 80 office chairs with five legs each and 20 round tables with three legs each. If after a month 40% of the chairs are damaged and have to be disposed of, calculate the total number of legs of furniture Kenzo has remaining in his company.
[Answer]The number of chairs that are disposed of after they're found to be damaged is 40 / 100 * 80 = 32. The number of chairs in good condition in Kenzo's company is 80 - 32 = 48. The 48 chairs have 48 * 5 = 240 legs. The round tables also have 20 * 3 = 60 legs. In total, the furniture in Kenzo's company has 60 + 240 = 300 legs. The answer is 300.

Question: A pet store owner had 12 birds, 9 puppies, 5 cats, and 15 spiders. Half the birds were sold and 3 puppies were adopted. Then, someone left the spider enclosure open and 7 of them went loose. How many animals does the pet store owner have left?
Answer: There are 12 / 2 = 6 birds left. There are 9 - 3 = 6 puppies left. There are 15 - 7 = 8 spiders left. The pet store owner has 5 + 6 + 6 + 8 = 25 animals left. The answer is 25.
[Question]A father and a son start approaching each other at the same time from opposite ends of a hallway that is 16m long. If the father is walking three times as fast as the son, at what distance from the father's end of the hallway will they meet?
[Answer]Since the father is walking 3 times as fast as his son, their speeds are in a ratio of 3:1 respectively. They started at the same time so they will cover distance at the same ratio of 3:1. Each portion of the distance they covered is 16 / (3 + 1) = 4m. The father covered three portions of the distance which is 3 * 4m = 12m from his end. The answer is 12.
