Question:

The Table given below shows the number of students having obtained different marks.

What is the mean marks per student?

Options:

13.5

12.25

15.5

14.25

Correct Answer:

Total number of students = 6 + 5 + 2 + 2 + 5 = 20

Mean marks = \(\frac{10 ×6+12 ×5+14 ×2+16 ×2+18 ×5}{20}\)

= \(\frac{60 + 60 + 28 + 32 + 90 }{20}\)

= = \(\frac{270}{20}\)

= 13.5
