假使醫生得病，病菌將會感染到手套內面；若病患得病，手套外面就會感染到病菌；若未得病的醫生或病患接觸到手套感染病菌的那一面，也會被傳染得病，因此為了防止這種情況，一般都會讓三位醫生用不同的手套進行手術。

但狀況來了，現在醫院裡只有藍色、白色各一副手套，該用兩怎麼辦呢？

醫生Ａ：「我和Ｂ各用一副，Ｃ就沒得用了。」
醫生Ｂ：「我一次戴兩副，藍色套在白色外面，每副手套可能有一面感染病菌，但另一面保證是無菌的。」

`在一座很深的高山上住著一群和尚，其中有一個老和尚以及不知道多少個小和尚，而他們都是超級聰明的。有一天老和尚對這群小和尚說他要選傳人，不過不知道會選幾個人。而他告訴他們在某一天晚上，在他們睡覺的時候，老和尚會在其中幾個人額頭上畫紅點。當然，不會驚醒他們。而當小和尚知道自己有被點到的那瞬間，就必須趕快來找老和尚學習。不過從宣布那一刻起，所有的人都不能照鏡子，也不能和其他人用任何方式溝通。換句話說，除了看到別人的頭以外，沒有任何方法可以知道自己的頭有沒有被點到。現在他們的作息是每天中午所有的人會在禪房聚一次，然後就會各自回到自己的寢室一直到隔天中午才會再見到其他人。就這樣過了幾天，晚上老和尚偷偷地在七個小和尚的頭上畫了紅點，而隔天（第一天）</summary><link

type='text'>「五間房子誰養魚」是一個非常困難的文字推理問題，就好像拼圖一樣，如果拼的不對，那兩個提示之間就會互相矛盾。我個人覺得最難的部分並不是找出每個提示中間的關係，而是要記住每個提示。所以我想出一個我覺得還不錯的方法來解這一類的問題，就是用拼的。首先畫一張表，再把每個提示變成變成一塊拼圖，接下來要做的就是把這些拼圖放入表中。變成看的見的拼圖有一個好處，就是圖片本身就是提示，它們之間的關係也被他們的形狀代表著。如果某個空格放不進這片拼圖，那代表這個提示和你要放的位置邏輯上有衝突。好吧！我知道看完還是霧煞煞，我這裡提供一個Excel 檔。我已經把每一個提示一一的變成拼圖，看你能不能把他放入表格中囉。注意，最後一定會有一格空格出現，因為別忘了，提示中都沒有出現魚。有興趣的可以從這裡得到檔案，不想下載的也可以從這裡看到拼圖會長怎樣。</summary><link rel='related' href='http://smartio.blogspot.com/2007/01/blog-post_07.html'
