Correct Option: D
On the basis of given graph in question ,
Number of students who got above 80% marks = 24 + 8 = 32
Total number of students = 2 + 4 + 12 + 26 + 35 + 42 + 72 + 48 + 24 + 8 = 273
∴ Required percent = | × 100 | Total number of students |
∴ Required percent = | × 100 = 11.72 % | 273 |
