Question
In a 240-litre mixture of milk and water, the amount of
milk is 50% more than the amount of water. How much milk should be added so that the ratio of milk to water becomes 7:4?Solution
ATQ,
Let the initial quantity of water be 'b' litres. Initial quantity of milk = '1.5b' litres. So, b + 1.5b = 240 Or, 2.5b = 240 Or, b = 96 Initial quantity of water = 96 litres Initial quantity of milk = 1.5 × 96 = 144 litres Let the required quantity be 'x' litres. So, (144 + x) : 96 = 7 : 4 Or,144 + x = 168 Or, x = 24
