I'll begin by extracting the relevant data from the image to calculate the total marks and percentage for each student. Please hold on for a moment while I process the image.It appears that the text extraction was not successful. The quality or format of the image might be affecting the OCR process.

Let's try a different approach. I'll enhance the image for better text extraction and attempt the process again.The text extraction is still unsuccessful, likely due to the quality or structure of the image.

To assist you further, could you provide the data manually, or possibly a clearer image? Alternatively, if you describe the structure (e.g., list of names with their respective scores), I can help with the calculations directly.
