A pipe can fill a tank in 6 hours , due to a leak in the tank it gets filled in7 hours. When the tank is full how much time will it take to empty the tank?

Open in App

Solution

tank filling rate = 1/6

time taken with leakage = 1/7

new tank filling rate = 1/7

therefore, rate of leakage = 1/6 - 1/7 = (7 - 6)/42 = 1/42

hence, it will take 42 hours to empty the tank, if the tank is full.
