## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following bar diagram, represents the use of different modes of travel to school by students in a certain locality of the town. Study the graph and answer the questions.

1. What is the percentage of students using Bus from that locality?

1. On the basis of given graph in question ,
Number of students who use bus = 150

 ∴ Required percentage = 150 × 100 660

##### Correct Option: C

On the basis of given graph in question ,
Number of students who use bus = 150

 ∴ Required percentage = 150 × 100 660

 Required percentage = 250 = 22 8 % 11 11

1. How many students use Bicycle and Rickshaw combined?

1. As per the given bar graph in question ,
Number of students who use Bicycle = 18
Number of students who use Rickshaw = 16

##### Correct Option: B

As per the given bar graph in question ,
Number of students who use Bicycle = 18
Number of students who use Rickshaw = 16
Bicycle and Rickshaw users = (18 + 16) × 10 = 340

1. How many students are coming from that locality?

1. On the basis of given graph in question ,
Total number of students = (6 + 15 + 11 + 18 + 16) × 10 = 66 × 10 = 660

##### Correct Option: D

On the basis of given graph in question ,
Total number of students = (6 + 15 + 11 + 18 + 16) × 10 = 66 × 10 = 660

Direction: Sales of books (in thousands} from six branches (B1, B2, B3, B4, B5, B6) of a publishing company are given below. Study the graph and answer the following questions.

1. If all the six branches are divided into three groups such that each group has equal performance on selling books, then the minimum difference of the number of books (in thousands) sold by the two members of any group is

1. As per the given bar graph in question , we have
B1 + B4 = B2 + B6 = B3 + B5 = 100000
B3 – B5 = 55 – 45 = 10 thousand
B4 – B1 = 80 – 20 = 60 thousand
B6 – B2 = 60 – 40 = 20 thousand

##### Correct Option: B

As per the given bar graph in question , we have
B1 + B4 = B2 + B6 = B3 + B5 = 100000
B3 – B5 = 55 – 45 = 10 thousand
B4 – B1 = 80 – 20 = 60 thousand
B6 – B2 = 60 – 40 = 20 thousand
∴ Minimum difference = 10

1. If each branch can increase the sale of books by 2%, then the total number of books (in thousands) sold by the company will be

1. According to given bar graph in question ,
Total sale of books from all branch = 300
Increase the sale of books by 2%,

 Required total sales = 300 × 102 100

##### Correct Option: B

According to given bar graph in question ,
Total sale of books from all branch = 300
Increase the sale of books by 2%,

 Required total sales = 300 × 102 = 306 thousand 100
