Let the capacity of the tank be ‘120’ litres {LCM (30, 40)} Efficiency of pipe ‘A’ = (120/30) = 4 litres/minute Efficiency of pipe ‘B’ = (120/40) = 3 litres/minute Quantity of water filled by pipe ‘A’ in 20 minutes = 4 × 20 = 80 litres Quantity of water to be filled = 120 – 80 = 40 litres Time taken by pipe ‘A’ and ‘B’ together to fill 40 litres of water = {40/(4 – 3)} = 40 minutes Total time taken = 20 + 40 = 60 minutes
