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 Anuj in all the five subjects are ?

331

Total marks of Anuj = 80% of 75 + 55% of 80 + 68% of 100 + 66% of 50 + 84% of 150

=   \(\frac{4}{5}\) × 75 + \(\frac{11}{20}\) × 80 +   \(\frac{17}{25}\) × 100 +   \(\frac{33}{50}\) × 50  +   \(\frac{21}{25}\) × 150

= 60 + 44 + 68 + 33 + 126

= 331
