The total marks obtained by Anuj in all the five subjects are ?
Answer & explanation
Correct answer: option 1
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
