## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the diagram and answer the questions. 1. If the total annual expenditure of family A is \$ 30,000 then money spent on food, clothes and house- rents is.

1. From the given bar diagram , we see
Total annual expenditure of family A = \$ 30,000
Expenditure of ( Food + clothes + house rent ) = 30 + 15 + 15 = 60%
∴ Required expenditure = Total annual expenditure of family A × 60%

##### Correct Option: A

From the given bar diagram , we see
Total annual expenditure of family A = \$ 30,000
Expenditure of ( Food + clothes + house rent ) = 30 + 15 + 15 = 60%
∴ Required expenditure = Total annual expenditure of family A × 60%

 ∴ Required expenditure = 30000 × 60 = \$ 18000 100

1. What fraction of the total expenditure is spent on Education in family A?

1. On the basis of given graph in question ,
Expenditure on education for family A = 20%
Total expenditure = 100%

 Required fraction = Expenditure on education for family A Total expenditure

##### Correct Option: C

On the basis of given graph in question ,
Expenditure on education for family A = 20%
Total expenditure = 100%

 Required fraction = Expenditure on education for family A Total expenditure

 Required fraction = 20 = 1 100 5

1. If the total annual expenditure of family B is \$ 10,000 then money spent on clothes during the year is

1. From the given bar diagram , we see
The total annual expenditure of family B = \$ 10,000
Percentage expenditure on clothes for family B = 15
∴ Required expenditure = 15% of Total annual expenditure

##### Correct Option: C

From the given bar diagram , we see
The total annual expenditure of family B = \$ 10,000
Percentage expenditure on clothes for family B = 15
∴ Required expenditure = 15% of Total annual expenditure

 Required expenditure = 10000 × 15 = \$ 1500 100

Direction: The sub divided bar diagram given below depicts H.S. Students of a school for three years. Study the diagram and answer the questions. 1. The percentage of the students passed with 2nd division in the year 2010 was

1. As per the given bar graph , we have
Total students in 2010 = 200
Students passed in 2nd division in 2010 = 60

 Required percentage = Students passed in 2nd division in 2010 × 100 Total students in 2010

##### Correct Option: A

As per the given bar graph , we have
Total students in 2010 = 200
Students passed in 2nd division in 2010 = 60

 Required percentage = Students passed in 2nd division in 2010 × 100 Total students in 2010

 Required percentage = 60 × 100 = 30% 200

1. The number of students passed with 3rd division in the year 2008 was

1. According to given bar graph , we have
Number of students passed in 2nd and 1st division in 2008 = 80
Total number of students passed in 2008 = 140
∴ Students passed in third division in 2008 = Total number of students passed in 2008 - Number of students passed in 2nd and 1st division in 2008

##### Correct Option: B

According to given bar graph , we have
Number of students passed in 2nd and 1st division in 2008 = 80
Total number of students passed in 2008 = 140
∴ Students passed in third division in 2008 = Total number of students passed in 2008 - Number of students passed in 2nd and 1st division in 2008
Students passed in third division in 2008 = 140 – 80 = 60
