Let's assume the tank has 12 litres capacity. The pipe can fill in 3 hours therefore efficiency= 12/3=4. Now the leak caused the tank to be filled in 3 1/2 hrs.
Total capacity/efficiency of pipe-efficiency of leak=time taken
ie,12/4-x=7/2
X=(28-24)/7= 4/7 which is the efficiency of d leak.
So time take by the leak to empty the tank is:
12รท 4/7 12*7/4= 7*3 = 21 hours
