Question
Pipe ‘A’ can fill a 210-litre tank in 21 hours. If
pipe ‘A’ is 25% more efficient than pipe ‘C’ whereas pipe ‘B’ is 50% more efficient than pipe ‘C’, then find the time (in minutes) taken by all the given three pipes to fill the same tank together.Solution
According to Question; Efficiency of pipe ‘A’ = (210/21) = 10 litres/hour Efficiency of pipe ‘C’ = 10 ÷ 1.25 = 8 litres/hour Efficiency of pipe ‘B’ = 8 × 1.5 = 12 litres/hour Time taken by all the pipes together to fill the tank = {210/(10 + 8 + 12)} = (210/30) = 7 hours Or, time taken by all three pipes together to fill the tank = 7 × 60 = 420 minutes
