Let the capacity of the tank be 120 litres {LCM (30 and 40)} Efficiency of pipe ‘A’ = 120 ÷ 30 = 4 litres/hour Efficiency of leak ‘A’ = 120 ÷ 40 = 3 litres/hour Combined efficiency of pipe ‘A’ and leak ‘A’ = 4 – 3 = 1 litre/hour Combined efficiency of pipe ‘A’, ‘B’ and leak ‘A’ = 120 ÷ 15 = 8 units/hour Efficiency of pipe ‘B’ = 8 – 1 = 7 units/hour Time taken by pipe ‘B’ and leak ‘A’ to fill the tank = 120 ÷ (7 – 3) = 30 hours
