The ages of 5 teachers in my school are 32 years 28 years 24 years 38 years and 30 years. Find their average age.
Given:
The ages of 5 teachers are 32 years 28 years 24 years 38 years and 30 years.
To do:
We have to find their average age.
Solution:
We know that,
$Average=\frac{Sum\ of\ observations}{Number\ of\ observations}$
Therefore,
The average age of the teachers$=\frac{32+28+24+38+30}{5}$
$=\frac{152}{5}$
$=30.4$
The average age of the teachers is 30.4 years.
