The bar graph given below shows the number of students (in hundred numbers) graduated from 4 different departments of a university, Mathematics (DOM), Physics (DOP), Chemistry (DOC) and English (DOE) during 3 consecutive years.

What is the average number of students that graduated from all the departments (in hundred numbers) for the year 2017?

Correct option is A

​​​Given:

Number of students graduated in 2017 (in hundreds):

D.O.M = 6

D.O.P = 6

D.O.C = 6

D.O.E = 7

Formula Used:
Average =$$\frac{\text{ (Sum of all values) }}{\text{ (Number of values)}}$$​​

Solution:

Average$$= \frac{6 + 6 + 6 + 7}{4} = \frac{25}{4} = 6.25$$ hundred students = 625 students
