Question
An inlet can fill a tank in 36 minutes, and an outlet
can drain it in 54 minutes. Find the time required to fill half the tank when both pipes are open.Solution
ATQ,
Let the total capacity of the tank be 108 litres (LCM of 36 and 54)
Efficiency of inlet = 108 ÷ 36 = 3 litres/minute
Efficiency of outlet = 108 ÷ 54 = -2 litres/minute
Required time = (0.5 × 108) ÷ (3 - 2) = 54 minutes
