A balloon is observed simultaneously from three points A, B and C on a straight road directly under it. The angular elevation at `B` is twice and at `C` is thrice that at `A` . If the distance between A and B is 200 metres and the distance between B and C is 100 metres, then find the height of balloon above the road.
