## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following histogram of wage distribution of different number of workers and answer the given questions.

1. The number of workers earning more than Rs. 940 but less than Rs. 960 is

1. As per the given above histogram , we can see
Number of workers whose wages between 940 to 950 = 5
Number of workers whose wages between 950 to 960 = 10
Required number of workers = Number of workers whose wages between 940 to 950 + Number of workers whose wages between 950 to 960

##### Correct Option: A

As per the given above histogram , we can see
Number of workers whose wages between 940 to 950 = 5
Number of workers whose wages between 950 to 960 = 10
Required number of workers = Number of workers whose wages between 940 to 950 + Number of workers whose wages between 950 to 960
Required number of workers = 5 + 10 = 15

1. Total number of workers surveyed is

1. According to given histogram , we have
Number of workers whose wages between 900 to 910 = 3
Number of workers whose wages between 910 to 920 = 2
Number of workers whose wages between 920 to 930 = 4
Number of workers whose wages between 930 to 940 = 9
Number of workers whose wages between 940 to 950 = 5
Number of workers whose wages between 950 to 960 = 10
Number of workers whose wages between 960 to 970 = 5
Number of workers whose wages between 970 to 980 = 3

##### Correct Option: C

According to given histogram , we have
Number of workers whose wages between 900 to 910 = 3
Number of workers whose wages between 910 to 920 = 2
Number of workers whose wages between 920 to 930 = 4
Number of workers whose wages between 930 to 940 = 9
Number of workers whose wages between 940 to 950 = 5
Number of workers whose wages between 950 to 960 = 10
Number of workers whose wages between 960 to 970 = 5
Number of workers whose wages between 970 to 980 = 3
Number of workers whose wages between 980 to 990 = 3
Number of workers whose wages between 990 to 1000 = 5
Total number of workers surveyed = 3 + 2 + 4 + 9 + 5 + 10 + 5 + 3 + 3 + 5 = 49

1. Number of workers who earn less than Rs. 950 is

1. On the basis of given histogram in question ,
Number of workers whose wages between 900 to 910 = 3
Number of workers whose wages between 910 to 920 = 2
Number of workers whose wages between 920 to 930 = 4
Number of workers whose wages between 930 to 940 = 9
Number of workers whose wages between 940 to 950 = 5

##### Correct Option: A

On the basis of given histogram in question ,
Number of workers whose wages between 900 to 910 = 3
Number of workers whose wages between 910 to 920 = 2
Number of workers whose wages between 920 to 930 = 4
Number of workers whose wages between 930 to 940 = 9
Number of workers whose wages between 940 to 950 = 5
Number of workers who earn less than Rs. 950 = 3 + 2 + 4 + 9 + 5 = 23

1. Number of workers who earn more than Rs. 950 is

1. As per the given above histogram , we can see
Number of workers whose wages between 950 to 960 = 10
Number of workers whose wages between 960 to 970 = 5
Number of workers whose wages between 970 to 980 = 3
Number of workers whose wages between 980 to 990 = 3
Number of workers whose wages between 990 to 1000 = 5

##### Correct Option: C

As per the given above histogram , we can see
Number of workers whose wages between 950 to 960 = 10
Number of workers whose wages between 960 to 970 = 5
Number of workers whose wages between 970 to 980 = 3
Number of workers whose wages between 980 to 990 = 3
Number of workers whose wages between 990 to 1000 = 5
Number of workers who earn more than Rs. 950 = 10 + 5 + 3 + 3 + 5 = 26

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. About 11% of the patients who got admitted to the hospital on that particular day were of age

1. According to given graph, we have

 11% of 35 = 35 × 11 = 3.85 ≈ 4 100

Patients between 35 years and 40 years = 4

##### Correct Option: D

According to given graph, we have

 11% of 35 = 35 × 11 = 3.85 ≈ 4 100

Patients between 35 years and 40 years = 4
Patients between 55 years and 60 years = 4
Therefore , required answer is option D.
