#### Data Interpretation

Direction: The sub- divided bar diagram given below depicts the result of B.Com. students of a college for 3 years. Study the graph and answer the given questions.

1. In which year, did the college have the best result for B. Com?

1. From the given bar diagram , we see
Total students in year 2006 = 170
Students who passed in year 2006 = 140

 Pass percentage :Year 2006 ⇒ 140 × 100 ≈ 82.35 ; 170

Total students in year 2007 = 190
Students who passed in year 2007 = 150
 Pass percentage : Year 2007 ⇒ 150 × 100 ≈ 78.94 ; 190

##### Correct Option: C

From the given bar diagram , we see
Total students in year 2006 = 170
Students who passed in year 2006 = 140

 Pass percentage :Year 2006 ⇒ 140 × 100 ≈ 82.35 ; 170

Total students in year 2007 = 190
Students who passed in year 2007 = 150
 Pass percentage : Year 2007 ⇒ 150 × 100 ≈ 78.94 ; 190

Total students in year 2008 = 240
Students who passed in year 2008 = 180
 Pass percentage : Year 2008 ⇒ 180 × 100 = 75% 240

Hence , correct answer is 2007 year .

1. What was the number of third divisions in 2006?

1. According to given bar graph , we have
Total passed students in year 2006 = 140
Students who passed in first division and second division = 80
Students who passed in third division in 2006
= Total passed students in year 2006 - Students who passed in first division and second division

##### Correct Option: A

According to given bar graph , we have
Total passed students in year 2006 = 140
Students who passed in first division and second division = 80
Students who passed in third division in 2006
= Total passed students in year 2006 - Students who passed in first division and second division
∴ Students who passed in third division in 2006 = 140 – 80 = 60

1. What was the pass percentage in 2008?

1. On the basis of given graph in question ,
Total students in the year 2008 = 240
Successful students = 180

 ∴ Required percentage = Successful students × 100 Total students in the year 2008

##### Correct Option: C

On the basis of given graph in question ,
Total students in the year 2008 = 240
Successful students = 180

 ∴ Required percentage = Successful students × 100 Total students in the year 2008

 ∴ Required percentage = 180 × 100 = 75% 240

1. How many percent of students passed in first division in 2007?

1. According to given bar graph , we have
Total students in year 2007 = 190
Students who passed in first division = 30

 Required percent = Students who passed in first division × 100 Total students in year 2007

 Required percent = 30 × 100 = 300 190 19

##### Correct Option: A

According to given bar graph , we have
Total students in year 2007 = 190
Students who passed in first division = 30

 Required percent = Students who passed in first division × 100 Total students in year 2007

 Required percent = 30 × 100 = 300 190 19

 Required percent = 15 15 % 19

Direction: The production figures of a perfume manufacturer are given in the form of percentage in sub-divided bar diagram. Study the diagram and answer the questions.
