Question

What is the approximate percentage of children have a level of diabetic more than $100$ mg per dl?

• A. $30\%$
• B. $40\%$
• C. $50\%$
• D. $23\%$

Answer 1

The correct option is D $23\%$

By referring the histogram, number of students with diabetic level:

$20-40$ is $5$ students

$40-60$ is $20$ students

$60-80$ is $35$ students

$80-100$ is $15$ students

$100-120$ is $10$ students

$120-140$ is $20$ students.

Total number of children $=105$.

Number of children have a level of diabetic more than $100$ mg per dl $=$ $10+15=15$.

Therefore, percentage children have a level of diabetic more than $100$ mg per dl $=$ $\frac{15}{105}=0.23\times 100\approx 23\%$.

Hence, option $D$ is correct.
