Solution
| Number of men | 1200 | x |
| Days | 35 | 25 |
\[1200 \times 35 = 25x\]
\[ \Rightarrow x = \frac{1200 \times 35}{25}\]
\[ = 1680\]
\[ \therefore \text{ Required number of men } = 1680 - 1200 = 480\]
\[\text{ Thus, an additional 480 men should join the existing 1200 men to finish the stock in 25 days } .\]
