Study the following table and answer the question:
Percentage of marks obtained by six students in five subjects A, B, C, D & E.

The total marks obtained by Amit in subjects A, B and C is what percent less than the total marks obtained by Vikram in subjects B, C, D and E?

Total marks obtained by Amit in subjects A, B and C = $$\frac{64}{100}\times75+\frac{65}{100}\times80+\frac{80}{100}\times100$$ = 48 + 52 + 80 = 180

Total marks obtained by Vikram in subjects B, C, D and E = $$\frac{70}{100}\times80+\frac{73}{100}\times100+\frac{84}{100}\times50+\frac{86}{100}\times150$$ = 56 + 73 + 42 + 129 = 300

Required percentage = $$\frac{300-180}{300}\times100$$ = 40%

Hence, the correct answer is Option C
