From the following table, how many patients were in the age group 40 – 60? Age (years) Less than 10 Less than 20 Less than 30 Less than 40 Less than 50 Less than 60 Less than 70 No. of patients 11 15 22 29 35 45 50 Correct Answer 16

Given:

We have to find the patient of the age group 40-60

Calculation:

Number of patient of age less than 40 is 29

Number of patient of age less than 50 is 35

⇒ Number of people whose age is 40 to 50 is (35 - 29) = 6

Number of patient of age less than 60 is 45

⇒ Number of people whose age is 50 to 60 is (45 - 35) = 10

∴ Total number of people of age 40 to 60 is (6 + 10) = 16
