In a mixture of 85 litres, the ratio of milk to water
is 2 : 3. If this ratio is to be 1 : 3, then what is the quantity of water needed to be added?Solution
Quantity of milk in the mixture = 85 × 2/5 = 34 liters Quantity of water in the mixture = 85 × 3/5 = 51 liters Let x liters water be added to the mixture then, 34/(51+ x) = 1/3 102 = 51 + x x = 102 - 51 = 51 litres
