Question
150 litres of mixture contains water and milk in the
ratio 5:6 respectively. If 40 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 = 150 – 40 = 110 litres Quantity of water in the final mixture = 110 x (5/11) + 40 = 90 litres Quantity of milk in the final mixture = 110 x (6/11) = 60 litres Ratio of water and milk in the final mixture = 90 : 60 = 3:2
