Question
A 120 litres mixture contains 40% milk and rest water.
How much water should be added to the mixture, such that milk constitutes 25% of the resultant mixture.Solution
Quantity of milk in the initial mixture = 0.4 X 120 = 48 litres Since, quantity of milk remained unchanged Therefore, total quantity of the resultant mixture = (48/0.25) = 192 litres Quantity of water to be added = 192 - 120 = 72 litres
