Question

8 pipes can fill a tank in 2 hours. How long will 5 pipes take to fill the same tank?

Answer 1

Answer:

If 2 hours is required by 8 pipes to fill a tank, then it takes 3.2 hours for 5 pipes to fill the tank

Step-by-step explanation:

Given

The time taken by 8 pipes to fill the tank completely= 2 hours

So, the time taken by 1 pipe to fill the tank = 2*8 = 16 hours

So, the time taken by 5 pipes to fill the tank = 16/5 = 3.2 hours

So, 3.2 hours is taken by 5 pipes to fill the tank
