## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the bar diagram and answer the following questions. The bar diagram shows the number of bicycles parked in the parking space of a hall at various points of time.

1. The charges for parking is \$ 1 per hour. What will be the total collection from 9 am to 7 pm?

1. On the basis of given graph in question ,
Given , The charges for parking = \$ 1 per hour
Number of cycles parked from 9 am to 7 pm.
= 95 + 75 + 85 + 65 + 75 + 55 + 65 + 45 + 55 + 35 + 45 = 695

##### Correct Option: D

On the basis of given graph in question ,
Given , The charges for parking = \$ 1 per hour
Number of cycles parked from 9 am to 7 pm.
= 95 + 75 + 85 + 65 + 75 + 55 + 65 + 45 + 55 + 35 + 45 = 695
∴ Collected amount = 695 × 1 = \$ 695

Direction: The bar graph given indicates the income of a firm. Study the graph and answer the questions given.

1. The average monthly income of the firm (in billion \$) is :

1. According to given bar graph , we have
Total income = 7 + 4 + 9 + 11 + 13 = \$ 44 billions
Number of months = 5

 Average income of the company = Total income Number of months

 Average income of the company = \$ 7 + 4 + 9 + 11 + 13 billion 5

##### Correct Option: C

According to given bar graph , we have
Total income = 7 + 4 + 9 + 11 + 13 = \$ 44 billions
Number of months = 5

 Average income of the company = Total income Number of months

 Average income of the company = \$ 7 + 4 + 9 + 11 + 13 billion 5

 Average income of the company = 44 = \$ 8.8 billion 5

1. The income in May is how many times to that of February?

1. From the given bar diagram , we see
The income in May = 13
The income in February = 4

##### Correct Option: A

From the given bar diagram , we see
The income in May = 13
The income in February = 4

1. During which month, the ratio of the income to that of the previous month is the largest?

1. According to given bar graph , we have
Income in February = \$ 4 billion
Income in March = \$ 9 billion
Required ratio = Income in March : Income in February

##### Correct Option: B

According to given bar graph , we have
Income in February = \$ 4 billion
Income in March = \$ 9 billion
Required ratio = Income in March : Income in February
∴ Required ratio = 9 : 4

1. Which period shows a steady increase of income?

1. According to given bar graph , we see
There was steady increase from March to May.

##### Correct Option: A

According to given bar graph , we see
There was steady increase from March to May. Hence , required answer is March to May .
