A
10 litres

B

C

D

Solution

Given:

The total quantity of the mixture is 60 litres.

In the mixture water is 20%.

After adding water, it will be 36% in the final mixture.

According to the question, we will add only water to the final mixture,

So, we will consider 100% of the water will be added to the final mixture so that in the final mixture the water will be 36%.

So, the ratio of the initial quantity of the mixture to the quantity of the water added to the mixture will be 4:1.

Let the initial quantity of the mixture be 4x, and the added water be x.

So, we can say,

∴ 15 liters of water should be added to the final mixture.
