问题 Two hundred multiples of seven are chosen at random, and 300 multiples of eight are chosen at random. Approximately what percentage of the 500 selected numbers are odd?

选项 A、20%
B、25%
C、40%
D、5O%
E、80%

答案A

解析 All multiples of 8 are even, and half of the multiples of 7 are odd; the multiples of 7 make up 2/5 of the total, so if 1/2 of those multiples of 7 are odd, then 1/5 of the total will be odd, or 20%.
