Let the total capacity of the tank be 100 units Efficiency of pipe ‘A’ = 100/20 = 5 units/hour Efficiency of pipe ‘B’ = 100/25 = 4 units/hour Tank filled in 14 hours = 14 × 5 = 70 units Therefore, required time taken to fill the remaining tank = (100 – 70)/(5 – 4) = 30 hours Therefore, total time taken = 14 + 30 = 44 hours
