Let capacity of the tank = 18 litres (lcm of 6 and 9) Efficiency of pipe ‘A’ = (18/6) = 3 litres/hour Efficiency of pipe ‘B’ = (18/9) = 2 litres/hour Efficiency of all the three pipes together = (18/4.5) = 4 litres/hour Efficiency of pipe ‘C’ = 4 – (3 + 2) = (-1) litre/hour {Negative sign shows that pipe ‘C’ is an outlet pipe} Required time taken = {(2/3) × 18)}/1 = 12 hours
