Question
110 litres of mixture contains water and milk in the
ratio 2:5 respectively. If 26 litres of the mixture is replaced by same quantity of water, then find the ratio of water and milk in the final mixture.Solution
Remaining quantity of the original mixture = 110 – 26 = 84 litres Quantity of water in the final mixture = 84 x (2/7) + 26 = 50 litres Quantity of milk in the final mixture = 84 x (5/7) = 60 litres Ratio of water and milk in the final mixture = 50 : 60 = 5:6
