- The ratio of rural to urban students is 4:7.

- Average marks for rural students are 65.

- Average marks for urban students are 63.

- To find the overall average percentage, we use the weighted average formula:

\text{Overall average} = \frac{(4 \times 65) + (7 \times 63)}{4 + 7}

- Simplifying, the overall average becomes:

\frac{260 + 441}{11} = \frac{701}{11} = 63.73

- Correct Answer: 63.73% (Option 1)
