there is a water tank. the capacity of the tank is 100 litres. one pipe is fitted at the top of the tank. also another pipe is fitted at the bottom of the tank. the pipe at the top allows 3 litres each minute to enter into the tank. the pipe at the bottom takes out 5 litres each minute from the tank. when the tank is completely filled with water both the pipes are opened. find how much time will be required for emptying the tank.

In one minute, 3 litres is filled, 5 litres is emptied.
Total loss in one minute = 2 litres.
Total water= 100 litres.
Let time taken to empty the tank = t.
2t = 100
t = 50 minutes.
Hope this helps.
