Direction: The subdivided bar diagram given below depicts the result of Class XII students of a school for three years. Study the diagram and answer the questions given below :

1. The percentage of students passed with Second class in the year 2000 is

1. On the basis of given graph in question ,
Total number of students in the year 2000 = 160
Number of students who stood second in the year 2000 = 50

 ∴ Required percentage = Number of students who stood second in the year 2000 × 100 Total number of students in the year 2000

 ∴ Required percentage = 50 × 100 160

Correct Option: D

On the basis of given graph in question ,
Total number of students in the year 2000 = 160
Number of students who stood second in the year 2000 = 50

 ∴ Required percentage = Number of students who stood second in the year 2000 × 100 Total number of students in the year 2000

 ∴ Required percentage = 50 × 100 160

 Required percentage = 125 = 31 1 % 4 4

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
