Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 91.
Explanation:
Since the number of students with marks 0% and above = 100
And students with marks 80% and above = 9
Son the students with marks less than 80% = (students with marks 0% and above - students with marks 80% and above) = 100 - 9 = 91.
Hence the required answer is 91.
