The recreation director at a local youth club surveyed the members to determine interest in two activities—a hiking trip and a softball game. Of the members surveyed, 60 percent were interested in the hiking trip and 75 percent were interested in the softball game. Of those who were interested in the softball game, 2/3 were also interested in the hiking trip. What percent of the members surveyed were not interested in either of the two activities?
选项
A、10%
B、15%
C、25%
D、35%
E、40%
答案
B
解析
设总人数为x,对hiking感兴趣的有60%,人数为0.6x,对softball感兴趣的人数为0.75x,其中2/3也对hiking感兴趣,即同时对hiking和softball感兴趣的人数为0.5x,只对hiking感兴趣的人数为0.1x,只对softball感兴趣的为0.25x,对hiking和softball都不感兴趣的为x-0-5x-0.25x-0 1x=0.15x,占比为15%,故答案为B。
