Correct Answer - Option 4 : Zero

Calculation:

Total marks obtained by student A = 60 + 70 + 50 + 30 = 210

Total maximum marks for student A = 350

Percentage of marks obtained by student A = (210/350) × 100 = 60%

Total marks obtained by student B = 80 + 70 + 60 + 15 = 225

Total maximum marks for student B = 375

Percentage of marks obtained by student B = (225/375) × 100 = 60%

Difference between the aggregate percentage = 60 - 60 = 0

∴ The difference between the aggregate percentage marks is zero.
