Question
A 320 litres mixture contains milk and water in the
ratio 3:1 respectively. If 30% of the mixture is replaced with the same quantity of water, then find the quantity of water in the new mixture.Solution
Quantity of water in the mixture initially = 320 × (1/4) = 80 litres Quantity of water removed = 80 × 0.3 = 24 litres Quantity of water added = 320 × 0.3 = 96 litres Quantity of water in the new mixture = 80 – 24 + 96 = 152 litres
