$\begin{array}{l}\text{According to the question,}\\
\begin{array}{l}
\text { Milk : Water }\\
\left.\begin{array}{lll}
7 & : & 5 \\
7 & : & 8
\end{array}\right) 3 \text { unit }
\end{array}\end{array}$
∴ Remember water is added and not milk, so make milk equal but here milk is already equal
$\begin{array}{l}
3 \text { units }=15 \text { litres } \\
1 \text { unit }=5 \text { litres } \\
8 \text { units }=40 \text { litres }
\end{array}$
Total quantity of water in the new mixture = 40 litres
