Question

A pipe can fill a tank in 8 hours. However, in case of outflow from a waste pipe in thebottom, the tank is filled in 12 hours. If the tank is full, how much time will the waste
pipe take to empty it?​

Answer 1

Answer:

tank filling rate = 1/8

time taken with leakage = 29 1/3 = 88/3

new tank filling rate = 3/88

therefore, rate of leakage = 1/8 - 3/88 = (11 - 3)/88 = 8/88 = 1/11

hence, it will take 11 hours to empty the tank, if the tank is full.
