Let the total capacity of the tank be 150 units Efficiency of pipe ‘A’ = 150/25 = 6 units/hour Efficiency of pipe ‘B’ = 150/30 = 5 units/hour Tank filled in 12 hours = 12 × 6 = 72 units Therefore, required time taken to fill the remaining tank = (150 – 72)/(6 – 5) = 78 hours Therefore, total time taken = 12 + 78 = 90 hours
