-
If 40 is the pass marks, percentage of students failed is
-
- 14.56
- 15.84
- 16.11
- 17.25
Correct Option: C
According to given graph in question ,
Number of students who got 40% or less marks = 2 + 4 + 12 + 26 = 44
Total number of students = 2 + 4 + 12 + 26 + 35 + 42 + 72 + 48 + 24 + 8 = 273
∴ Required percent = | × 100 | Total number of students |
∴ Required percentage = | × 100 = 16.11 % | 273 |
