Study the following table carefully and answer the questions given below it.
What is the difference between the total marks obtained by students G and F in all the subjects together ?
Total marks obtained by G = Summation of (Percentage * Max marks) = 78% * 75 + 69% * 75 + 65% * 50 + 76% * 100 + 75% * 150 + 58% * 100 = 389.25
Total marks by F = 75% * 75 + 78% * 75 + 86% * 50 + 84% * 100 + 78% * 150 + 69% * 100 = 427.75
So, the difference = 427.75 - 389.25 = 38.5
