Question
A solution of milk and water has (x + 30) litres of milk,
which is (x + 20) litres less than the water. If the water content is 100 litres, calculate the ratio of milk to water.Solution
ATQ,
Quantity of water in the mixture = x + 30 + x + 20 = (2x + 50) litres
Therefore, 2x + 50 = 100
Or, 2x = 50
Or, x = 25
Therefore, quantity of milk in the mixture = x + 30 = 55 litres
Required ratio = 55 : 100 = 11 : 20
