假設現在有十二袋一元硬幣..每袋的硬幣數量一樣..
但係現在知道其中一袋全部都係假的..
現只知真的硬幣重十克..假的硬幣重九克..
諗諗最少可以用磅的形式多少次便可以知道答案..
(答案請附上解釋)
(當然答案唔可以話靠運氣啦..hehee..)

[updated:LAST EDITED ON Dec-12-03 AT 11:53 AM (GMT)]壹次！
首先排好第一袋至第十二袋硬幣，
以第一袋抽一個硬幣、第二袋抽兩個..........至第十二袋抽十二個硬幣，
將抽出的硬幣一起放到磅上，看看少了多少克便知是那一袋假了。

唔知係咪好細個果陣，已經對智力遊戲產生興趣，
幾歲人仔，人地扭計買公仔書，我就扭買"智力世界"，
到而家都仲係好有興趣，成日o係internet 玩呢類o野！
不過年紀大，機器壞，思維都開始慢落o黎，
需要多D 時間先拆到喇！
