Question 60

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?

Solution

The average marks of students B, C, D and F in Math = $$\frac{\frac{92}{100}\times150+\frac{80}{100}\times150+\frac{74}{100}\times150+\frac{84}{100}\times150}{4}$$

= $$\frac{\frac{150}{100}\left[92+80+74+84\right]}{4}$$

= $$\frac{\frac{150}{100}\left[330\right]}{4}$$

= $$\frac{495}{4}$$

= 123.75

Hence, the correct answer is Option C
