## Introduction to Data Interpretation

#### Data Interpretation

Direction: Shown below is the multiple bar diagram depict- ing the changes in the roll strength of a college in four faculties from 2001- 02 to 2003-04. 1. The percentage of students in Science faculty in 2001- 2002 is

1. From the given bar diagram , we see
Number of students in Science in 2001 - 2002 = 400
Total students in 2001 – 2002 = 1350

 ∴ Required percentage = Number of students in Science in 2001 - 2002 × 100 Total students in 2001 – 2002

##### Correct Option: D

From the given bar diagram , we see
Number of students in Science in 2001 - 2002 = 400
Total students in 2001 – 2002 = 1350

 ∴ Required percentage = Number of students in Science in 2001 - 2002 × 100 Total students in 2001 – 2002

 ∴ Required percentage = 400 × 100 = 29.6% 1350

Direction: The following bar diagram shows the percentage of Hindus, Sikhs and Muslims in a state during the years from 2004 to 2007. Examine the bar diagram and answer the following questions. 1. If the total population of the state in 2005 was 5 million, then the Hindu population was [1 million = 10,00,000]

1. On the basis of given graph in question ,
Total population of the state in 2005 = 5 million
Percent of the Hindu population in 2005 = 35%
The Hindu population in 2005 = 35% of 5 million

##### Correct Option: D

On the basis of given graph in question ,
Total population of the state in 2005 = 5 million
Percent of the Hindu population in 2005 = 35%
The Hindu population in 2005 = 35% of 5 million

 Hindus = 5000000 × 35 = 1750000 100

1. If the total population of the state in 2004 was 5 lakhs, then the Hindu and Muslim population in that year was

1. From the given bar diagram , we see
Total population of the state in 2004 = 5 lakhs
Total percent of Hindu and Muslim population of the state in 2004 = 30 + 25 = 55%
Total ( Hindus + Muslims ) population in 2004 = 55% of 5 lakhs

##### Correct Option: B

From the given bar diagram , we see
Total population of the state in 2004 = 5 lakhs
Total percent of Hindu and Muslim population of the state in 2004 = 30 + 25 = 55%
Total ( Hindus + Muslims ) population in 2004 = 55% of 5 lakhs

 Hindus + Muslims = 500000 × 55 = 275000 100

1. The ratio between the Hindu and Sikh population in 2004 was

1. According to given bar graph , we have
The Hindu population in 2004 = 30%
And Sikh population in 2004 = 45%
Required ratio = The Hindu population in 2004 : Sikh population in 2004

##### Correct Option: C

According to given bar graph , we have
The Hindu population in 2004 = 30%
And Sikh population in 2004 = 45%
Required ratio = The Hindu population in 2004 : Sikh population in 2004
∴ Required ratio = 30 : 45 = 2 : 3

Direction: In the following questions, a graphical representation of income and expenditure of 5 persons during the month of January has been given. Read the graph and answer the questions. 1. What is the income range of the persons?

1. As per the given bar graph , we have
The income of the 4th person = \$ 8.75
The income of the 5th person = \$ 4.25
Income range = The income of the 4th person - The income of the 5th person

##### Correct Option: D

As per the given bar graph , we have
The income of the 4th person = \$ 8.75
The income of the 5th person = \$ 4.25
Income range = The income of the 4th person - The income of the 5th person
∴ Income range = \$ (8.75 – 4.25) thousand = \$ 4500
