Question
A mixture of milk and water contains (x + 25) litres of
milk, which is (x + 55) litres less than the quantity of water. If the total quantity of water in the mixture is 105 litres, find the ratio of milk to water.Solution
ATQ,
Quantity of water in the mixture = x + 25 + x + 55 = (2x + 80) litres
Therefore, 2x + 80 = 105
Or, 2x = 25
Or, x = 12.5
Therefore, quantity of milk in the mixture = x + 25 = 37.5 litres
Required ratio = 37.5 : 105 = 5 : 14
