Hello all.
I have been told about a riddle which I have found very funny. So here it is.
There's a steep wall 100 meters in height, which has two hooks in it: one at the top, and one at a height of 50 meters (half way down to the ground). An alpinitst, standing on top of the wall, has a 75-meter rope and a knife, and he needs to get down off the wall.
How can he do it?
P.S. Those who already know the solution, please don't pubish it, for the riddle is purposed for the pleasure of solving it!
P.P.S.: It's not very difficult, but beautiful.
