Correct answer: A
Assume tank capacity is 45 Liters.
Given that the first pipe fills the tank in 9 hours.
So its capacity is 45 / 9 = 5 Liters/ Hour.
Second pipe fills the tank in 5 hours.
So its capacity is 45 / 5 = 9 Liters/Hour. If both pipes are opened together, then combined capacity is 14 liters/hour.
To fill a tank of capacity 45 liters, Both pipes takes 45 / 14 = 3.21 Hours.
