Let the capacity of the cistern = 144 units Then, efficiency of pipe ‘A’ = 144/18 = 8 units/minute Efficiency of pipe ‘B’ = 144/16 = 9 units/minute Efficiency of pipe ‘C’ = 144/12 = 12 units/minute So, combined efficiency of pipes ‘A’, ‘B’ and ‘C’ = 8 + 9 – 12 = 5 units/minute 50% of the cistern’s capacity = 72 units Therefore, time taken by all 3 pipes together to fill 50% of the cistern = 72/5 = 14.4 minutes
