Question
A 480 litre mixture contains only milk and water in the
ratio 7:5 respectively. If 'x' litre of water is added to the mixture, then ratio of milk and water become 7:6 respectively. Find the value of 'x'.Solution
Initial quantity of Milk = 480 × (7/12) = 280 litres Initial quantity of Water = 480 × (5/12) = 200 litres ATP, (280) : (200 + x) = 7 : 6 Or, 1680 = 1400 + 7x 7x = 280 'x' = 40
