A pipe can fill a tank in 10 hours, while another pipe
can empty it in 15 hours. If both pipes are opened simultaneously, in how many hours will the tank be full?Solution
ATQ, Filling pipe's rate = 1/10 Emptying pipe's rate = 1/15 Net filling rate = 1/10 - 1/15 = 1/30 The tank will be full in 30 hours.
