I need help interpreting a frequency distribution table for 100 candidates. Some parts are obscured and formatting is unusual. I need to find x, the modal class, median, and mean.

The image provided contains a frequency distribution table for marks obtained by 100 candidates. The table is partially obscured and contains some unusual formatting. Based on the context of the questions (determining $x$, modal class, median, mean), we will interpret the table as follows:

The first row represents the class intervals for marks. We will assume these are continuous classes with a width of 1, centered around the given values.
The second row, labeled "Frequency", contains the frequencies for each class. There appear to be two rows of numbers under "Frequency". Given that frequencies must be whole numbers and the total frequency is 100, we will use the numbers that are most likely to be whole number frequencies. The first set of numbers under "Frequency" seems to be the intended frequencies, with
