Question

What is the difference between the percentage of marks obtained by student ‘E’ in Chemistry and Maths together and the percentage of marks obtained by student ‘A’ in Social Studies and English together?

• A. 6
• B. 8
• C. 12
• D. 14
• E. None of these

Answer 1

The correct option is B

8

Marks of E (Chemistry + Maths) = 71 + 119 = 190

Percentage marks $=\frac{190}{250}\times 100=76\%$

Marks of A (Social Studies + English) = 138 + 32 = 170

Percentage marks $=\frac{170}{250}\times 100=68\%$

$\therefore$ Difference in percentage marks = 76 - 68 = 8%
