be taken out and the same quantity of water added to it so that the ratio of milk and water
becomes 3:2?
​

Answer 1

AddingAnswer:

On adding 15 liters of water to the mixture of 45 liters and making its final Volume to 60 liters will give milk to water mixture in the ratio of 3: 2

Step-by-step explanation:

Milk in container earlier=(4/5)*45=36 L

Water in container earlier=(1/5)*45=9 L

Now required milk: water ratio=3:2

Suppose we add x L of water in the container, then;

36/(9+x)=3:2

solving we get x=15 L

Therefore 15 L of water required to make a ratio of 3:2

So, adding 15 liters of water to the mixture of 45 liters and making its final Volume to 60 liters will give milk to water mixture in the ratio of 3: 2
