## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following multiple bar graph carefully and answer the questions

1. What is the ratio of numbers of working women to the non-working women in the year 2009?

1. According to given bar graph , we have
The number of non-working women in the year 2009 = 40 millions
The number of working women in the year 2009 = 70 millions
Required ratio = The number of working women in the year 2009 : The number of non-working women in the year 2009

##### Correct Option: A

According to given bar graph , we have
The number of non-working women in the year 2009 = 40 millions
The number of working women in the year 2009 = 70 millions
Required ratio = The number of working women in the year 2009 : The number of non-working women in the year 2009
∴ Required ratio = 70 : 40 = 7 : 4

1. The number of non-working women in the year 2010 was approximately (correct up to an integer) what percent of total number of working as well as non-working women in that year?

1. From the given bar diagram , we see
The number of non-working women in the year 2010 = 35 millions
The number of working women in the year 2010 = 85 millions
Total number of working and non-working women in the year 2010 =85 + 35 = 120 millions

 Required percentage = The number of non-working women in the year 2010 × 100 Total number of working and non-working women in the year 2010

##### Correct Option: C

From the given bar diagram , we see
The number of non-working women in the year 2010 = 35 millions
The number of working women in the year 2010 = 85 millions
Total number of working and non-working women in the year 2010 =85 + 35 = 120 millions

 Required percentage = The number of non-working women in the year 2010 × 100 Total number of working and non-working women in the year 2010

 Required percentage = 35 × 100 ≈29% 120

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. Percentage of increase in Science students in 2003-04 over 2001- 2002 is

1. On the basis of given graph in question ,
Number of students in Science in 2001 - 2002 = 400
Number of students in Science in 2003 - 2004 = 600
Increase = 600- 400 = 200

 Required percentage increase = Increase × 100 Number of students in Science in 2001 - 2002

##### Correct Option: B

On the basis of given graph in question ,
Number of students in Science in 2001 - 2002 = 400
Number of students in Science in 2003 - 2004 = 600
Increase = 600- 400 = 200

 Required percentage increase = Increase × 100 Number of students in Science in 2001 - 2002

 Required percentage increase = 200 × 100 = 50% 400

1. The percentage of students in Law faculty in 2003-04 is

1. As per the given bar graph , we have
Number of students in Law in 2003 - 04 = 250
Total students in 2003-04 = 1600

 ∴ Required percentage = Number of students in Law in 2003 - 04 × 100 Total students in 2003-04

##### Correct Option: C

As per the given bar graph , we have
Number of students in Law in 2003 - 04 = 250
Total students in 2003-04 = 1600

 ∴ Required percentage = Number of students in Law in 2003 - 04 × 100 Total students in 2003-04

 ∴ Required percentage = 250 × 100 = 15.6% 1600

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
