Question

How many litres of a 12 litre mixture containing milk and water in the ratio of 2 : 3 be replaced with pure milk so that the resultant mixture contains milk and water in equal proportion?

Answer 1

Answer:

2 Liters

Step-by-step explanation:

Hey Mate,

12 litre mixture containing milk and water.

The mixture ratio of milk and water is 2 : 3

So, 40% milk and 60% water is in it.

40% of Milk = 4.8 litres

60% of Water = 7.2 litres of water.

Milk and Water in equal proportion.

So, 50% = Milk and 50% = Water.

We need to reduced 1.2 litres of water to maintain equal proportion.

By remove 1.2 litres of water from the original mixture  which contain 60% water,

We need to remove  

$\frac{1.2}{0.6}$  litres of the mixture = 2 litres.
