## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following figure shows the number of students (in thousands) admitted and passed out per year in a college during years 2000 to 2004. Study the figure and answer the questions.

1. The ratio of the number of students admitted in the year 2002 to the average of the number of students passed out in the years 2003 and 2004. is

1. According to given bar graph , we have
Number of students admitted in the year 2002 = 8 thousands
Total number of students passed out in the years 2003 and 2004 = 9 + 9 = 18 thousands
Number of given years = 2
Required ratio = Number of students admitted in the year 2002 : Average of the number of students passed out in the years 2003 and 2004

##### Correct Option: B

According to given bar graph , we have
Number of students admitted in the year 2002 = 8 thousands
Total number of students passed out in the years 2003 and 2004 = 9 + 9 = 18 thousands
Number of given years = 2
Required ratio = Number of students admitted in the year 2002 : Average of the number of students passed out in the years 2003 and 2004

 Required ratio = 8 : 18 2

Required ratio = 8 : 9

1. In which of the two years, the pass percentage of students was between 60 and 70?

1. On the basis of given graph in question ,
Number of passed student in 2000 = 4 thousands
Number of admitted student in 2000 = 6 thousands

 Passing percentage in 2000 = 4 × 100 6

 Passing percentage in 2000 = 200 = 66 2 % 3 3

Number of passed student in 2001 = 6 thousands
Number of admitted student in 2001 = 9 thousands

##### Correct Option: A

On the basis of given graph in question ,
Number of passed student in 2000 = 4 thousands
Number of admitted student in 2000 = 6 thousands

 Passing percentage in 2000 = 4 × 100 6

 Passing percentage in 2000 = 200 = 66 2 % 3 3

Number of passed student in 2001 = 6 thousands
Number of admitted student in 2001 = 9 thousands
 Passing percentage in 2001 = 6 × 100 = 200 = 66 2 % 9 3 3

1. During 2000 to 2003, the ratio of the total number of the students passed out to the total number of students admitted is

1. As per the given bar graph , we have
During 2000 to 2003,
Total students admitted = (6 + 9 + 8 + 12) thousands = 35 thousands
Total students passed = (4 + 6 + 6 + 9) thousands = 25 thouseands
∴ Required ratio = Total students passed : Total students admitted

##### Correct Option: D

As per the given bar graph , we have
During 2000 to 2003,
Total students admitted = (6 + 9 + 8 + 12) thousands = 35 thousands
Total students passed = (4 + 6 + 6 + 9) thousands = 25 thouseands
∴ Required ratio = Total students passed : Total students admitted
Required ratio = 25 : 35 = 5 : 7

1. The percent increase in the number of students admitted in the year 2003 over that in 2001 is

1. According to given bar graph , we have
Number of students admitted in 2001 = 9000
Number of students admitted in 2003 = 12000
Increase = 12000 - 9000 = 3000

 Percentage increase = Increase × 100 Number of students admitted in 2001

##### Correct Option: B

According to given bar graph , we have
Number of students admitted in 2001 = 9000
Number of students admitted in 2003 = 12000
Increase = 12000 - 9000 = 3000

 Percentage increase = Increase × 100 Number of students admitted in 2001

 Percentage increase = 100 % = 33.3% 3

Direction: Study the following bar graph showing the percentage of children who can read at first-grade level, grouped by their grade level in an Indian state.
For example, in 2008, 82% of the children from Standard 3 could read a text from Standard 1. Now answer the following question based on this graph.

1. In the year 2010, what is the approximate value of average of all Std 1, 2, 3, 4, 5 children who could read the Std 1 text?

1. From the given bar diagram , we see that the number of children in respective standard is not known.

##### Correct Option: D

From the given bar diagram , we see that the number of children in respective standard is not known.So , required answer is option D .
