Let the capacity of the tank be ‘140’ litres {LCM (20, 35)} Efficiency of pipe ‘A’ = (140/20) = 7 litres/minute Efficiency of pipe ‘B’ = (140/35) = 4 litres/minute Quantity of water filled by pipe ‘A’ in 17 minutes = 17 × 7 = 119 litres Quantity of water to be filled = 140 – 119 = 21 litres Time taken by pipe ‘A’ and ‘B’ together to fill 21 litres of water = {21/(7 – 4)} = 7 minutes Total time taken = 17 + 7 = 24 minutes
