Answer 2

$\LARGE\sf {\underline{\underline\green{Required \: Answer:-}}}$

1.)

Arranging the ages in ascending order, we get:

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

We find that the age of the oldest teacher is 54 years and the age of the youngest teacher is 23 years.

2.)

Range of teachers = (54 - 23) years = 31 yrs.

3.)

Mean age of the teachers:

$\tt \implies\dfrac{23 + 26 + 28 + 32 + 33 + 35 + 38 + 40 + 41 + 54}{10}years$

$\tt{ = \dfrac{350}{10}years = 35 \: years. }$
