[七嘴八舌] 女友问了我一个智力题，我居然答不出来,求助

有3个人去投宿,一晚30元，三个人每人掏了10元凑够30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 = 27 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,那一元去哪里了你知道吗?

一元钱哪去了?

每个人付了9块钱，一共27元，这27元里已经包含了老坂的25元跟服务生藏起来的2元，所以在未尾就没必要再加上服务生藏起来的2元，而是加上他们退回来的3元。就刚好是30元。
也可以这样理解，他们自己退回来了3元，再加上服务生藏起来的2元，就是5元，剩下的都在老板那里。
这题目一开始就把人带进一个误导区，让人觉得少了一块钱，其实并没有少。

其实根本就没有这一块钱,只是个误导

按爱因斯坦相对论解释，两个情况是混淆了时间和空间，将他们分开来解释就行了，要不只选给，要不只选收，试试！
