A 400 liter mixture of milk and water contains 86% milk. How many more liters of water should be added so that the proportions of milk and water become equal?


288 liter.

The volume of milk will remain same at ${86 × 400}/100$ = 344 liters. The amount of water at present is 400 - 344 = 56 liters. We need to make the volume of water equal to that of the milk. So we have to add 344 - 56 = 288 liters of water.
