### Question

A 200 liter mixture of milk and water contains 64% milk. How many more liters of water should be added so that the proportions of milk and water become equal?

**A**

56 liter.

**B**

57 liter.

**C**

55 liter.

**D**

59 liter.

**Soln.**

**Ans: a**

The volume of milk will remain same at ${64 × 200}/100$ = 128 liters. The amount of water at present is 200 - 128 = 72 liters. We need to make the volume of water equal to that of the milk. So we have to add 128 - 72 = 56 liters of water.
