## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following multiple bar graph carefully and answer the questions 1. What is the ratio of the number of women working in the year 2006 to the number of women working in the year 2010?

1. As per the given bar graph , we have
The number of working women in the year 2006 = 50 millions
The number of working women in the year 2010 = 85 millions
Required ratio = The number of working women in the year 2006 : The number of working women in the year 2010

##### Correct Option: D

As per the given bar graph , we have
The number of working women in the year 2006 = 50 millions
The number of working women in the year 2010 = 85 millions
Required ratio = The number of working women in the year 2006 : The number of working women in the year 2010
∴ Required ratio = 50 : 85 = 10 : 17

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
