# The enrolment in a school during six consecutive years was as follows:

1555, 1670, 1750, 2013, 2540, 2820

Find the mean enrolment of the school for this period

**Solution:**

We use the basic formula of mean to solve the problem.

Mean enrollment = sum of numbers of enrollments/Total numbers of years

Total no. of years = 6

The enrollments in a school during six consecutive years = 1555, 1670, 1750, 2013, 2540, 2820

Mean enrollment = sum of numbers of enrollments/Total numbers of years

=(1555 +1670 +1750 + 2013 + 2540 + 2820)/6

=12348/6

=2058

Thus, the mean enrollment of the school is 2058.
