Question
A 240-litre solution contains milk and water in the ratio
3:5 respectively. How much milk should be added to make the ratio of milk to water 7:10?Solution
ATQ;
Initial quantity of milk = (3/8) × 240 = 90 litres
Initial quantity of water = (5/8) × 240 = 150 litres
Let the required quantity of milk to be added be 'y' litres.
So, (90 + y) :150 = 7:10
Or, 90 + y = 105
Or, 'y' = 15
