问题 单项选择题

有100人参加运动会的三个项目,每人至少参加一项,其中未参加跳远的有50人,未参加跳高的有60人,未参加赛跑的有70人,问至少有多少人参加了不只一项活动?()

A.7

B.10

C.15

D.20

答案

参考答案:B

解析:由题意可知,参加跳远的有50人,参加跳高的有40人,参加赛跑的有30人;要使得参加不止一项的人数最少,那么重复参加的人全部都是参加3个项目的。50+40+30-100=20人次,因为重复参加的人都是3个项目,所以被重复计算了2次,则多出的人数是这部分人实际人数的2倍,可得20÷2=10人。故正确答案为B。

Cameron thought of himself as merely organized.He certainly did not consider that he took great pains over anything ,he did just enough to get it right.Exactly right, of course as he was fond of telling his staff, “if it’s not exactly right, it’s wrong”.Occasionally a worker might be sad on hearing these words, because it meant another hour or so of going over the same bit of work, correcting the mistakes which Cameron had patiently pointed out.And doing the corrections exactly right of course.

Strangely enough ,his department had the reputation for performing the highest quality work in the company ,and it was seen, and not only by those who worked in the department ,as a sort of elite(出类拔萃)unit.Those programs that had to work first time, straight out of the box, Cameron’s men got those.“It’s mission(任务)critical—give it to Cameron” was almost a catch—phrase with his team.

It helped that Cameron was not merely particular about things.He wanted things done just so ,not because of a personal taste ,but because he had discovered through patient experimentation that this was the best way for it to be done.
