Question
A mixture contains 70 litres milk and rest is water.
When 20 litres milk and 22 litres water is added to the mixture, the ratio of milk to water becomes 3 : 2. Find the initial quantity of mixture.Solution
Let initial quantity of water be βnβ litres. So,
(70 + 20) : (n + 22) = 3 : 2 Or,
90 : (n + 22) = 3 : 2 Or,
n + 22 = 60 Or,
n = 38 Therefore, required quantity of mixture
= 70 + 38
= 108 litres
