1. What is the percentage of production of sandal perfume during the year 1995 over that during 1997?

1. As per the given graph in question ,
Percentage production of sandal perfume in 1995 = 20%
Percentage production of sandal perfume in 1997 = 20%

##### Correct Option: A

As per the given graph in question ,
Percentage production of sandal perfume in 1995 = 20%
Percentage production of sandal perfume in 1997 = 20%
Hence , Production of sandal perfume remained same.

1. What is the ratio of percentage production of rose perfume during 1995 to that during the year 1997?

1. On the basis of given graph in question ,
Percentage production of rose perfume in 1995 = 45%

∴ Required ratio = Percentage production of rose perfume in 1995 : Percentage production of rose perfume in 1997

##### Correct Option: B

On the basis of given graph in question ,
Percentage production of rose perfume in 1995 = 45%
Percentage production of rose perfume in 1997 = 30%

Required ratio = 45 : 30 = 3 : 2

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 number of students passed with Second class in the year 2002 is

1. According to given bar graph , we have
Number of students passed with First class in the year 2002 = 80
Total number of students passed with 1st and 2nd division in the year 2002 = 130
Number of students who passed with second class in 2002 = Total number of students passed with 1st and 2nd division in the year 2002 - Number of students passed with First class in the year 2002

##### Correct Option: C

According to given bar graph , we have
Number of students passed with First class in the year 2002 = 80
Total number of students passed with 1st and 2nd division in the year 2002 = 130
Number of students who passed with second class in 2002 = Total number of students passed with 1st and 2nd division in the year 2002 - Number of students passed with First class in the year 2002
∴ Number of students who passed with second class in 2002 = 130 – 80 = 50

1. The number of students passed with Third class in the year 2002 is

1. On the basis of given graph in question ,
Number of students who passed with third class in 2002 = 10

##### Correct Option: B

On the basis of given graph in question ,
Number of students who passed with third class in 2002 = 10
Hence , required answer is option B .

1. The percentage of students passed with First class in the year 2001 is

1. From the given bar diagram , we see
Number of students passed with First class in the year 2001 = 60
Total number of students passed in the year 2001 = 120

 Required percentage = Number of students passed with First class in the year 2001 × 100 Total number of students passed in the year 2001

##### Correct Option: A

From the given bar diagram , we see
Number of students passed with First class in the year 2001 = 60
Total number of students passed in the year 2001 = 120

 Required percentage = Number of students passed with First class in the year 2001 × 100 Total number of students passed in the year 2001

 Required percentage = 60 × 100 = 50% 120
