Accepted Answer

Average marks = 6.795 (option C) A class of 44 students took a 5-question exam. Each question carries a fixed positive mark and there is no penalty for wrong or skipped answers. We need to find the average score per student, which equals the total marks earned by the entire class divided by the number of students.
