Question

The following table shows the marks obtained by two students in different subjects :

	Student A	Maximum Marks	Student B	Maximum Marks
English	60	100	80	150
Psychology	70	100	70	100
History	50	100	60	100
Sanskrit	30	50	15	25

 

The difference in the mean aggregate percentage marks of the students is

1. 2.5%
2. 13.75%
3. 1.25%
4. Zero

Answer 1

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.
