Study the following table and answer the question:
Percentage of marks obtained by six students A, B, C, D, E and in five subjects.
What are the average marks of students B, C, D and F in Math?
The average marks of students B, C, D and F in Math =Â $$\frac{\frac{92}{100}\times150+\frac{80}{100}\times150+\frac{74}{100}\times150+\frac{84}{100}\times150}{4}$$
=Â $$\frac{\frac{150}{100}\left[92+80+74+84\right]}{4}$$
=Â $$\frac{\frac{150}{100}\left[330\right]}{4}$$
=Â $$\frac{495}{4}$$
= 123.75
Hence, the correct answer is Option C
