Study the following table and answer the question: Percentage of marks obtained by six students A, B, C, D, E and F in five subjects.  Subjects →   Students ↓ English  (Out of 50)   Math  (Out of 150)  Science  (Out of 80)   Hindi  (Out of 75)   Social Studies   (Out of 100) A 70 90 65 64 88 B 84 92 75 68 49 C 66 80 85 80 84 D 62 74 75 88 60 E 54 64 55 72 85 F 72 84 65 60 65 What are the average marks of students B, C, D and F in Math?

125.5 82.5 123.75 120.75

123.75

Total marks of B , C , D & F = ( 92% + 80% + 74% + 84% ) of 150 =  \(\frac{330}{100}\) × 150 = 495 Average = \(\frac{495}{4}\) = 123.75
