    给大家出一道数学题,娱乐一下

     
    答案就发在评论里就好,呵呵!题目如下:
     
     
    有3个人去投宿,一晚三十元.三个人每人掏了10元凑够三十元交给了老板. 后来老板说今天优惠只要25元就够了,拿出5元命令服务生退还给他们, 服务生偷偷藏起了2元, 然后,把剩下的3元钱分给了那三个人,每人分到1元.这样,一开始每人掏了10元,现在又退回1元,也就是10-1=9,每人只花了9元钱, 3个人每人9元,3 X 9 = 2 7元 + 服务生藏起的2元=29元,还有一元钱去了哪里???此题在新西兰面试的时候曾引起巨大反响. 有谁知道答案呢?

    他们现付了30元钱。老板退5元。他们又从5元中付服务生2元钱。其实他们实际付了27元钱。30-5+2=27元
