Question

A 350 liter mixture of milk and water contains 56% milk. How many more liters of water should be added so that the proportions of milk and water become equal?

A

42 liter.

B

43 liter.

C

41 liter.

D

45 liter.

Soln.
Ans: a

The volume of milk will remain same at ${56 × 350}/100$ = 196 liters. The amount of water at present is 350 - 196 = 154 liters. We need to make the volume of water equal to that of the milk. So we have to add 196 - 154 = 42 liters of water.
