The table below displays a student's marks in four subjects across the first and second semester examinations for a particular year.
What is the approximate cumulative percentage of the student's marks for the entire year?
Show answer & explanation
Correct answer: C
Explanation
Total marks obtained = (40 + 45) + (70 + 80) + (35 + 40) + (55 + 65)= 430
Maximum marks for the entire year = 2 × (50 + 100 + 50 + 100)= 600
Cumulative percentage = 430/600 × 100= 72%
