Let the capacity of the tank be 300 litres {LCM (50 and 60)} Efficiency of pipe ‘A’ = 300 ÷ 50 = 6 litres/hour Efficiency of leak ‘A’ = 300 ÷ 60 = 5 litres/hour Combined efficiency of pipe ‘A’ and leak ‘A’ = 6 – 5 = 1 litre/hour Combined efficiency of pipe ‘A’, ‘B’ and leak ‘A’ = 300 ÷ 30 = 10 units/hour Efficiency of pipe ‘B’ = 10 – 1 = 9 units/hour Time taken by pipe ‘B’ and leak ‘A’ to fill the tank = 300 ÷ (9 – 5) = 75 hours
