A pipe can fill a tank in 6 hours,but due to a leakage it took 8 hours to fill the tank .if the tank is full, in what time will the tank become empty due to the leakage?

Rate of filling a tank in one hour= 1/6 *100=16.66%
Rate of filling tank with a leakage in one hour =1/8*100=12.5%
Rate of leakage in one hour =16.66% - 12.5%=4.16%
So tank will be empty in 24 hours(by using unitary method)
Rate of
