From a container, 6 liters milk was drawn out and was replaced by water. Again 6 liters of mixture was drawn out and was replaced by the water. Thus the quantity of milk and water in the container after these two operations is 9:16. The quantity of mixture is:

Correct Answer: 15

Explanation:

Let quantity of mixture be x liters.

Suppose a container contains x units of liquid from which y units are taken out and replaced by Water. After operations , the quantity of pure liquid = $x 1 - \frac{y}{x} n$ units, Where n = no of operations .

So, Quantity of Milk = $x 1 - \frac{6}{x} 2$

Given that, Milk : Water = 9 : 16

=> Milk : (Milk + Water) = 9 : (9+16)

=> Milk : Mixture = 9 : 25

Therefore, $\frac{x 1 - \frac{6}{x} 2}{x} = \frac{9}{25}$

=> x = 15 liters
