Find the modal class mark.
Answer Details
To find the modal class mark, we need to first identify the class with the highest frequency, which in this case is the class with marks 20-29 (16 students). The modal class mark is the midpoint of this class, which is calculated by adding the lower and upper limits of the class and dividing by 2:
Modal class mark = (20 + 29) / 2 = 24.5
Therefore, the modal class mark is 24.5, which is option (C).
