Question
A mixture contains 100 litres milk and rest is water.
When 50 litres milk and 30 litres water is added to the mixture, the ratio of milk to water becomes 5 : 4. Find the initial quantity of mixtureSolution
Let initial quantity of water be ‘n’ litres. So,
(100 + 50) : (n + 30) = 5 : 4 Or,
150 : (n + 30) = 5 : 4 Or,
n + 30 = 120 Or,
n = 90 Therefore, required quantity of mixture
= 100 + 90
= 190 litres
