Correct Answer - Option 2 : 2%
Calculation:
Percentage of marks scored by student A in all the 6 semesters = 74 + 79 + 73 + 78 + 72 + 86 = 462%
Percentage of marks scored by student E in all the 6 semesters = 66 + 76 + 71 + 81 + 89 + 92 = 475%
∴ The approximate absolute difference between the overall percentage of A and E for 6 semesters = (475% - 462%)/6
⇒ 13/6 = 2.1%
⇒ 2%
