Let the total capacity of the tank be 60 units Efficiency of pipe ‘A’ = 60/20 = 3 units/hour Efficiency of pipe ‘B’ = 60/30 = 2 units/hour Tank filled in 11 hours = 11 × 3 = 33 units Therefore, required time taken to fill the remaining tank = (60 – 33)/(3 – 2) = 27 hours Therefore, total time taken = 11 + 27 = 38 hours
