A 300 liter mixture of milk and water contains 70% milk. How many more liters of water should be added so that the proportions of milk and water become equal?


120 liter.


121 liter.


119 liter.


123 liter.

Ans: a

The volume of milk will remain same at ${70 × 300}/100$ = 210 liters. The amount of water at present is 300 - 210 = 90 liters. We need to make the volume of water equal to that of the milk. So we have to add 210 - 90 = 120 liters of water.
