Select an option to attempt

Explanation

Student A:

Total marks obtained = $60 + 70 + 50 + 30 = 210$ Total maximum marks = $350$ Percentage of marks = $(\frac{210}{350}) \times 100 = 60$ %

Student B: Total marks obtained = $80 + 70 + 60 + 15 = 225$ Total maximum marks = $375$ Percentage of marks = $(\frac{225}{375}) \times 100 = 60$ %

Difference in Aggregate Percentage: $60% - 60% = 0$

Thus, the difference in aggregate percentage marks is zero.
