Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 5.6
The total no. of students obtaining less than 50 marks = 45 + 78 + 110 + 142 = 375
the total no. of students obtaining 60 marks or more = 120 + 100 + 80 + 55 = 355
required percentage = (20/355) × 100 = 5.634
