I was given a very interesting puzzle for the last round that I found a little odd given the actual duties of the role. The puzzle goes as follows: You are on a boat in the middle of a lake/ocean/pool (point being that the body of water is contained and no water moves in and out of the system.) On the boat, you are holding a ball. At this state, the water level is L0. Afterwards, you drop the ball into the water and it sinks into the water (fully submerged) until it hits the bottom. Given this change in the system, the water level is recorded as L1. The question is, is L1 less than, equal to, or greater than L0?
