Let the capacity of the tank be ‘30’ litres {LCM (15, 30)} Efficiency of pipe ‘A’ = (30/15) = 2 litres/minute Efficiency of pipe ‘B’ = (30/30) = 1 litres/minute Quantity of water filled by pipe ‘A’ in 13 minutes = 13 × 2 = 26 litres Quantity of water to be filled = 30 – 26 = 4 litres Time taken by pipe ‘A’ and ‘B’ together to fill 4 litres of water = {4/(2 – 1)} = 4 minutes Total time taken = 13 + 4 = 17 minutes
