Question

a pipe can fill a tank in 10 hours. due to a leak in the bottom , it fills the tank in 20 hours,. if the tank is full, how much time will the leak take to empty it?

Answer 1

Answer:

5 hrs

Step-by-step explanation:

Think about it this way. If a pipe is taking twice as long to fill the tank with the leak then it should take twice as less time to empty it. :-)

Answer 2

The leak would take 20 hours to empty it.

Step-by-step explanation:

Since we have given that

Time taken by a pipe = 10 hours

Due to a leak, time taken by a pipe = 20 hours

We need to find the time taken by the leak to empty it.

So, it becomes,

$\dfrac{1}{20}-\dfrac{1}{10}\\\\=\dfrac{1-2}{20}\\\\=\dfrac{-1}{20}$

So, the leak would take 20 hours to empty it.
