I have a couple of riddles for you. Why are manhole covers round? That's strictly speaking not a riddle but it's a good way to find out how someone goes about solving problems.
Another riddle that recived much discussion around the office was a riddle about a plane on a conveyor belt. So the questions is; is it possible for a plane to take off if it is sitting on a conveyor belt that is moving at the same speed as the plane but in the opposite direction? For example the plane is moving forward at 20 km per hour so the belt is moving in the opposite direction at 20 km per hour. Is it possible for the plane to take off?
I wont tell u the answer of these. Feel free to email me your suggested answers though.
