Question

$70$ number of student's height are measured in cm as shown in the histogram. How many students have heights more than $180$ cm?

• A. $40$
• B. $63$
• C. $38$
• D. $32$

Answer 1

The correct option is D $32$

The given histogram represents the height of $70$ students in $cm$.

For finding the number of students having a height of more than $180cm$, we need to add the heights of the bars representing the bars $180-200,200-220,220-240$

The height of the bar, representing the number of students is:

$180-200\to 10$

$200-220\to 15$

$220-240\to 7$

Therefore, number of students having height more than $180cm=10+15+7$

$=32$

Hence, $32$ students have height more than $180cm$.
