Question
A mixture contains 84 litres milk and rest is water.
When 36 litres milk and 24 litres water is added to the mixture, the ratio of milk to water becomes 5 : 3. Find the initial quantity of mixture.Solution
Let initial quantity of water be ‘n’ litres. So,
(84 + 36) : (n + 24) = 5 : 3 Or,
120 : (n + 24) = 5 : 3 Or,
n + 24 = 72 Or,
n = 48 Therefore, required quantity of mixture
= 84 + 48
= 132 litres
