A mixture contains milk and water in the ratio 5:3. If 48 liters of water is added, the ratio becomes 5:5. Find the initial quantity of milk.
120 liters
Let milk = 5x and water = 3x litres. Adding 48 litres of water gives a new ratio of 5:5, meaning new water equals milk.
\(5x = 3x+48 \Rightarrow 2x=48 \Rightarrow x=24\).
Initial quantity of milk: \(5\times24 = 120\) litres.
Hence, the initial quantity of milk is 120 litres.
