## Introduction to Data Interpretation

#### Data Interpretation

Direction: The Expenditure of a family in a month is represented by a Pie-chart. Read it carefully to answer the questions.

1. The ratio of the amount spent on food and clothes is

1. As per the given pie chart in question ,
The corresponding angle of expenditure on food = 150°
The corresponding angle of expenditure on clothes = 30°
Required ratio = The corresponding angle of expenditure on food : The corresponding angle of expenditure on clothes

##### Correct Option: C

As per the given pie chart in question ,
The corresponding angle of expenditure on food = 150°
The corresponding angle of expenditure on clothes = 30°
Required ratio = The corresponding angle of expenditure on food : The corresponding angle of expenditure on clothes
Required ratio = 150° : 30°= 5 : 1

1. The percentage of money spent on food compared to house rent is

1. As per the given pie chart in question ,
The corresponding angle of expenditure on food = 150°
The corresponding angle of expenditure on house rent = 120°
Change in expenditure = The corresponding angle of expenditure on food - The corresponding angle of expenditure on house rent = 150 - 120 = 30°

 Required percent = Change in expenditure × 100 The corresponding angle of expenditure on house rent

##### Correct Option: A

As per the given pie chart in question ,
The corresponding angle of expenditure on food = 150°
The corresponding angle of expenditure on house rent = 120°
Change in expenditure = The corresponding angle of expenditure on food - The corresponding angle of expenditure on house rent = 150 - 120 = 30°

 Required percent = Change in expenditure × 100 The corresponding angle of expenditure on house rent

 Required percent = 30 × 100 = 25% 120

1. The total money spent on clothes and miscellaneous is :

1. On the basis of given pie chart in question ,
The corresponding angle for expenditure on clothes = 30°
The corresponding angle for expenditure on miscellaneous = 60°
Since total amount of expenditure is not given.

##### Correct Option: A

On the basis of given pie chart in question ,
The corresponding angle for expenditure on clothes = 30°
The corresponding angle for expenditure on miscellaneous = 60°
Since total amount of expenditure is not given.
Hence , option A is correct answer .

Direction: The following pie-chart shows the percentage distribution of the expenditure incurred in publishing a book. Read the pie-chart and answer the questions.

1. If for a certain quantity of books, the publisher has to pay \$ 30600 as printing cost, then the amount of royalty cost to be paid for these books is :

1. According to given pie chart in question ,
Percentage of printing cost = 20%
Percentage of Royalty cost = 15%
Printing cost = \$ 30600
∵ 20% ≡ \$ 30600

 ∴ 1% ≡ 30600 20

 ∴ Required paid amount = Printing cost × Percentage of Royalty cost Percentage of printing cost

##### Correct Option: C

According to given pie chart in question ,
Percentage of printing cost = 20%
Percentage of Royalty cost = 15%
Printing cost = \$ 30600
∵ 20% ≡ \$ 30600

 ∴ 1% ≡ 30600 20

 ∴ Required paid amount = Printing cost × Percentage of Royalty cost Percentage of printing cost

 ∴ Required paid amount = 30600 × 15 = \$ 22950 20

1. If 5500 copies are published and the transportation cost on them amount to \$ 82500 then the selling price of the book so that the publisher can earn a profit of 25% is :

1. As per the given pie chart in question ,
Total number of published copies = 5500
Transportation cost = 10%
Transportation cost = \$ 82500
∵ 10% ≡ \$ 82500
∴ 100% ≡ \$ 825000

 ∴ Cost for publishing 1 book = 825000 = \$ 150 5500

##### Correct Option: B

As per the given pie chart in question ,
Total number of published copies = 5500
Transportation cost = 10%
Transportation cost = \$ 82500
∵ 10% ≡ \$ 82500
∴ 100% ≡ \$ 825000

 ∴ Cost for publishing 1 book = 825000 = \$ 150 5500

For a profit of 25% ,
 ∴ Required S.P. = 150 × 125 = \$ 187.50 100
