Rope Escape

Rajeev is trapped atop a building 200m high. He has with him a rope 150m long.There is a hook at the top where he stands.

Looking down, he notices that midway between him and the ground, at a height of 100m, there is a ledge with another hook. In his pocket lies a Swiss knife.

How might he be able to come down using the rope, the two hooks and the Swiss knife?

The solution is to split the rope into 50, 100 m and then create a nose at the end of the 50 m rope. In the nose slide the 100 m rope so that you can reach the 100m hook.

Once at the 100m hook, slide out the complete 100 m rope from the nose and go down.
