Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e 42%.
| Understanding/Application |
| Number of students who got 20 or more marks = 14 + 19 + 6 + 3 = 42 |
|
Total number of students = 13 + 15 + 18 + 12 + 14 + 19 + 6 + 3 = 100 Thus, the required percentage = (42 × 100)/100 = 42% |
