is 64 litres

Answer 2

Answer:

The 25% of the capacity of the vessel is 64 litres.

Given:

A vessel is full of pure milk.

$\frac{1}{4}^{th}$ is taken out and replaced with water. If this process in repeated thrice, the milk left was found to be 108 liters.  

To find:

25% of the capacity of the vessel.

Solution:

$\frac{1}{4}^{th}$ of the vessel is replaced by water thrice. Let x be the quantity of pure milk.

$x \times \frac{3}{4} \times \frac{3}{4} \times \frac{3}{4}$=108

x=$108 \times\frac{64}{27}$

x=256=total capacity

25% of the vessel  =  $256 \times \frac{25}{100}$ =64 litres.
