Initially two cups of same volume are filled with milk upto $\frac{3}{5}$ th and $\frac{4}{5}$ th of their volumes. Water is then filled. Then two mixtures are mixed and poured into a jug. Find the ratio of water to milk in the mixture. (Campus Recruitment, 2008)

No answer key was printed for this question.
Explanation
Let the volume of each of the two cups be $x$. Then, volume of milk in the first cup $=\frac{3}{5}x$. Volume of water in the first cup $=\frac{2}{5}x$. Volume of milk in the second cup $=\frac{4}{5}x$. Volume of water in the second cup $=\frac{x}{5}$. $$\therefore \quad \text{Ratio of water to milk in the jug}=\left(\frac{2}{5}x+\frac{x}{5}\right):\left(\frac{3}{5}x+\frac{4}{5}x\right)=\frac{3}{5}x:\frac{7}{5}x=3:7.$$
