- We need to find the approximate value of the question mark in the equation:

$$\sqrt{(? + 68.77)} \times 5.03 = 24.99\% \text{ of } 541.12.$$

- Calculate 24.99% of 541.12: this is approximately $0.25 \times 541 \approx 135$.

- Simplify by estimating: $135 \approx \sqrt{(? + 68.77)} \times 5$.

- Divide both sides by 5: $(\sqrt{(? + 68.77)}) \approx \frac{135}{5} \approx 27$.

- To isolate the square root, approximate: $(? + 68.77) \approx 27^2 = 729$.

- Subtract 68.77: $? \approx 729 - 68.77 \approx 660$.

- This matches option 3.

- The correct answer is: Option 3: 660
