Question

The table below shows the sugar contents in an individual of different age groups, where below 100mg/dl is considered as safe, between $100$ and $125$ mg/dl is considered at risk but not called as diabetic, and above $125$ mg/dl is stated as diabetic.

Age Group	< 100mg/dL	100-125mg/dL	>125	Total
18-25	9	22	17	48
26-35	16	48	34	98
36-45	19	35	40	94
Older than 45	12	27	21	60
Total	56	132	112	300

According to the data, which age group had the smallest percentage of people with a healthy blood sugar level?

• A. $18-25$
• B. $26-35$
• C. $36-45$
• D. Older than $45$

Answer 1

Answer: (B)

$26-35$

For the group $18-25$,

As per table, the percentage of people with < 100mg/dl sugar $=$ $100\times \frac{9}{48}=18.75\%$

For the group $26-35$,

As per table, the percentage of people with < 100mg/dl sugar $=$ $100\times \frac{16}{98}=16.32\%$

For the group $36-45$,

As per table, the percentage of people with < 100mg/dl sugar $=$ $100\times \frac{19}{94}=20.21\%$

For the group: Older than $45$,

As per table, the percentage of people with < 100mg/dl sugar $=$ $100\times \frac{12}{60}=20\%$

So, according to data, age group $26-35$ has the smallest percentage of people with healthy blood sugar level (i.e. $<100$ mg / dl).
