Question

A pipe can fill the tank in 20 min and another pipe can fill the tank in 30 min. After returning, a man noticed that the tank did not fill due to leakage in bottom. If he fixes the leakage than the tank was filled in 3 minutes. In how much time that leakage will emptied the tank?

Answer 1

Answer:

Step-by-step explanation:

Pipe 1 = 20 minutes

Pipe 2= 30 minutes

With no leakage, the tank will be filled in = (1/20 + 1/30)⁻¹ = 12 minutes

Time for leakage = 50 -12 = 48 minutes due to leakage
