## Introduction to Data Interpretation

#### Data Interpretation

Direction: The diagram shows the age-distribution of the patients admitted to a hospital on a particular day. Study the diagram and answer the questions.

1. Percentage of patients of age less than 45 years, who got admitted to the hospital on that day is approximately equal to

1. On the basis of given graph in question ,
Total number of patients = 1 + 4 + 8 + 7 + 5 + 4 +3 + 2 + 1 = 35
Patients of age less than 45 years = 1 + 4 + 8 = 13

 Required percent = Patients of age less than 45 years × 100 Total number of patients

##### Correct Option: C

On the basis of given graph in question ,
Total number of patients = 1 + 4 + 8 + 7 + 5 + 4 +3 + 2 + 1 = 35
Patients of age less than 45 years = 1 + 4 + 8 = 13

 Required percent = Patients of age less than 45 years × 100 Total number of patients

 Required percent = 13 × 100 ≈ 37% 35

1. Number of patients of age more than 40 years and less than 55 years, who got admitted to the hospital on that day is

1. According to given graph, we have
Number of patients of age between 40 years to 45 years = 8
Number of patients of age between 45 years to 50 years = 7
Number of patients of age between 50 years to 55 years = 5

##### Correct Option: A

According to given graph, we have
Number of patients of age between 40 years to 45 years = 8
Number of patients of age between 45 years to 50 years = 7
Number of patients of age between 50 years to 55 years = 5
Required answer = 8 + 7 + 5 = 20

1. Total number of patients of age more than 55 years, who got admitted to the hospital is

1. On the basis of given graph in question ,
Number of patients of age between 55 years to 60 years = 4
Number of patients of age between 60 years to 65 years = 3
Number of patients of age between 65 years to 70 years = 2
Number of patients of age between 70 years to 75 years = 1

##### Correct Option: D

On the basis of given graph in question ,
Number of patients of age between 55 years to 60 years = 4
Number of patients of age between 60 years to 65 years = 3
Number of patients of age between 65 years to 70 years = 2
Number of patients of age between 70 years to 75 years = 1
Required answer = 4 + 3 + 2 + 1 = 10

1. Number of patients of age between 55 years to 60 years, who got admitted to the hospital on that day is

1. According to given diagram in question , we can see
Number of patients of age between 55 years to 60 years , who got admitted to the hospital = 4 patients

##### Correct Option: B

According to given diagram in question , we we can see
Number of patients of age between 55 years to 60 years , who got admitted to the hospital = 4 patients
Hence , correct answer is option B.

Direction: Following histogram depicts the range of heights of students in a class of 60 students. Study the same and answer the questions.

1. Group which contains maximum number of students is

1. From the given above histogram , we can see
Number of students in 150 – 160 class interval = 25

##### Correct Option: B

From the given above histogram , we can see
Number of students in 150 – 160 class interval = 25 , which is maximum .
