Fixed Fast Battery Drain Problem

Two taps X and Y are fixed to a water tank. If only X is opened, it drains out the full tank of water in 20 minutes. If both X and Y are opened, then they drain out the full tank of water in 15 minutes. If only Y is opened, how long does it take to drain out the full tank of water?

Figure shows four cells fixed on a board. Draw lines to indicate how you will connect their terminals with wires to make a battery of four cells.

If in the previous problem the battery is being charged with a current of 5 amp, in what direction will current flow inside the battery, and what will be the reading of the voltmeter

Mahesh has certain number of problems with him. He can solve some fixed number of problems every hour. After solving for 5 hours, he is left with 384 problems. If he had solved for 10 hours, he is left with 144 problems to solve. Find the number of problems with Mahesh initially.
