偷金繩

一日不BLOG如隔三秋,又甘啱同事MARTIN問起我一條幾好玩的IQ題,所以即刻寫落BLOG,如果你有興趣不防留個言並寫個答案出黎,大家分享一下! 希望你可以同我一樣可以係三分鐘內就解決左條IQ題啦!

問題:
在某廟宇裏有兩條用金造的繩子，各長100米，從廟頂伸展到地面上一米。兩條繩距離一米。
假設繩子能承受一個人的重量而不斷。
假設小偷除了爬金繩之外，便無法到達綁着金繩的橫樑之上。
現在有個小偷想偷走金繩，他只有一把刀，而且他最多可以從十米高處跳下來而不死。
問小偷最多可偷走多少米的金繩？

In a temple, there have two 100 metre-long golden ropes. They tie on the pillar that under the ceiling and freely hang beside the pillar. The tail of the ropes freely swing in the air at 1 metre above the ground.

A thief who want to steal the ropes. Assume the rope can stand the weight of a human and there exists no way the theif can reach the pillar without climb on the rope. Provided that the theif will not die when jump down from the height that leave the ground with 10 metres height or below.

Now the question is how long of the ropes in total that the thief can steal in maximum without damage the temple.
