In a mixture of 28 litres, the ratio of milk and water is 5:2. If 2 litres of water is
added to the mixture, find the ratio of milk and water in the new mixture.​

Answer 1

Explanation:

Given: In a mixture of 28 litres , the ratio of milk and water is 5:2.

Solution:

Let quantity of milk be 5x litres,then quantity of water will be 2x litres.

Total quantity if mixture is given to be 28 litres.

Therefore,

5x+2x=28

7x=28

x=28/7

x=4

Quantity of milk in the mixture =5x=5×4=20litres

Therefore,quantity of milk in the mixture is 20 litres.
