Correct Answer: 5 litres


Solution : Let the quantity of milk and water in the mixture be $5x$ and $3x$.
Quantity of water added $=$ 7 litres
The new quantity of water in the mixture $= 3x+7$ litres
According to the question,
$\frac{(5x)}{(3x+7)} = \frac{1}{2}$
⇒ $10x = 3x+7$
⇒ $7x=7$
⇒ $x=1$
So, the quantity of milk $= 5x =$ 5 litres
Hence, the correct answer is 5 litres.
