Question
Pipe 'A' is 3 times as efficient as pipe 'B'. Pipe 'C',
which is one-third as efficient as pipe 'B', can fill a tank alone in 36 hours. Find difference between time taken by pipe 'C' to fill 25% of the tank and time taken (in minutes) by pipe 'A' to fill the tank completely.Solution
Let the efficiency of pipe 'C' be 'x' litres/hour.
So, total capacity of the tank = '36x' litres.
Efficiency of pipe 'A' = x Ă— 3 Ă— 3 = '9x' litres/hour
So, time taken by pipe 'A' to fill the tank = 36x / 9x = 4 hours
And, time taken by pipe 'C' to fill 25% of the tank = (36x Ă— 0.25) / x = 9 hours
So, required difference = 9 - 4 = 5 hours = 5 Ă— 60 = 300 minutes
