Mean = 35 years

Explanation:

Given: Ages (in years) of 10 teachers in a school:

32, 28, 54, 41, 38, 40, 23, 33, 26, 35.

Sum of the ages = 32 + 28 + 54 + 41 + 38 + 40 + 23 + 33 + 26 + 35 = 350

Number of terms = 10

Mean age of the teachers =  sum of terms / number of terms

= 350 / 10

= 35

Mean age of the teachers = 35 years.
