Question

What is the approximate percentage of children have a level of diabetic less than $60$ mg per dl?

• A. $30\%$
• B. $40\%$
• C. $57\%$
• D. $23\%$

Answer 1

Answer: (C)

$57\%$

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 $=105$.

Children have a level of diabetic less than $60$ mg per dl $=$ $35+20+5=60$.

Therefore, percentage of children having level of diabetic less than $60$ mg per dl $=$ $\frac{60}{105}=0.57\times 100\approx 57\%$.

Hence, option $C$ is correct.
