The following table shows the marks obtained by two students, Raj, And Rohit in different subjects.

What is the difference between Rohit and Raj's percentage of aggregate marks?

Correct option is D

Given:

The marks obtained by Raj and Rohit in different subjects

Formula Used:

Percentage = $$\frac{Part\ Value}{Total \ Value} \times 100$$​​

Solution:

Total marks obtained by Raj in all subjects = 37 + 45 + 42 + 32 = 156

Percentge of aggregate marks =$$\frac{156}{200} \times 100 = 78\%$$​​

Total marks obtained by Rohit in all subjects = 48 + 30 + 45 + 35 = 158

Percentage of aggregate marks =$$\frac{158}{200}\times 100 = 79\%$$​​

Difference in percentage = 79 - 78 = 1%
