Let the capacity of the tank be ‘200’ litres {LCM (25, 40)} Efficiency of pipe ‘A’ = (200/25) = 8 litres/minute Efficiency of pipe ‘B’ = (200/40) = 5 litres/minute Quantity of water filled by pipe ‘A’ in 16 minutes = 16 × 8 = 128 litres Quantity of water to be filled = 200 – 128 = 72 litres Time taken by pipe ‘A’ and ‘B’ together to fill 72 litres of water = {72/(8 – 5)} = 24 minutes Total time taken = 16 + 24 = 40 minutes
