• A. $3$
• B. $5$
• C. $10$
• D. $2$

Answer 1

Answer: (C)

$10$

$\Rightarrow$ From given histogram we are going to form frequency distribution table:

$Ages$ $\left(Years\right)$	$No.ofteachers$
$20-25$	$4$
$25-30$	$5$
$30-35$	$6$
$35-40$	$3$
$40-45$	$2$
$45-50$	$5$

$\Rightarrow$ From above table we can see, the number of teachers more than $35$ years old $=3+2+5=10$
