## Introduction to Data Interpretation

#### Data Interpretation

Direction: The bar graph given below shows the total number of students in six sections of a class VI of a certain school. Using this graph, answer the question. 1. The percentage of students in section C out of the total students in class VI is approximately

1. On the basis of given graph in question ,
Number of the students in section C = 31
Total number of the students in class VI = 34 + 35 + 31 + 32 + 33 + 34 = 199

 Required percentage = Number of the students in section C × 100 Total number of the students in class VI

##### Correct Option: D

On the basis of given graph in question ,
Number of the students in section C = 31
Total number of the students in class VI = 34 + 35 + 31 + 32 + 33 + 34 = 199

 Required percentage = Number of the students in section C × 100 Total number of the students in class VI

 Required percentage = 31 × 100 = 15.57% 199

1. The ratio of the students in section B and section C is

1. From the given bar graph , we have
Number of the students in section B = 35
Number of the students in section C = 31
Required ratio = Number of the students in section B : Number of the students in section C

##### Correct Option: C

From the given bar graph , we have
Number of the students in section B = 35
Number of the students in section C = 31
Required ratio = Number of the students in section B : Number of the students in section C
Required ratio = 35 : 31

1. What is the total number of students in class VI ?

1. As per the given bar graph , we see
Number of students in section A = 34
Number of students in section B = 35
Number of students in section C = 31
Number of students in section D = 32
Number of students in section E = 33
Number of students in section F = 34

##### Correct Option: C

As per the given bar graph , we see
Number of students in section A = 34
Number of students in section B = 35
Number of students in section C = 31
Number of students in section D = 32
Number of students in section E = 33
Number of students in section F = 34
Total number of students = 34 + 35 + 31 + 32 + 33 + 34 = 199

1. What is the ratio of the number of students in section A to that in section C ?

1. On the basis of given graph in question ,
Number of students in section A = 34
Number of students in section C = 31
Required ratio = Number of students in section A : Number of students in section C

##### Correct Option: D

On the basis of given graph in question ,
Number of students in section A = 34
Number of students in section C = 31
Required ratio = Number of students in section A : Number of students in section C
Required ratio = 34 : 31

1. Which two sections have the same number of students?

1. On the basis of given graph in question ,
Section A = section F = 34

##### Correct Option: B

On the basis of given graph in question ,
Section A = section F = 34
Hence , two sections A and F have the same number of students 34 .
