## Introduction to Data Interpretation

#### Data Interpretation

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. The central angle of the sector corresponding to the expenditure incurred on Royalty is :

1. On the basis of given pie chart in question ,
Percentage expense on royalty = 15%
Percent of total expenditure = 100%
Corresponding angle for total expenditure = 360°
∵ 100% ≡ 360°

 ∴ Required angle = Corresponding angle for total expenditure × Percentage expense on royalty = 54° Percent of total expenditure

##### Correct Option: C

On the basis of given pie chart in question ,
Percentage expense on royalty = 15%
Percent of total expenditure = 100%
Corresponding angle for total expenditure = 360°
∵ 100% ≡ 360°

 ∴ Required angle = Corresponding angle for total expenditure × Percentage expense on royalty = 54° Percent of total expenditure

 ∴ Required angle = 360 × 15 = 54° 100

Direction: Study the pie chart and answer the given questions. The total expenditure of a company for a particular month is Rs. 60000. The various heads of expenditure I to IV are indicated in a pie chart given below. These heads are :
I. Raw materials
II. Conveyance
III. Electricity

1. What percentage of total expenditure is on raw materials?

1. On the basis of given pie chart in question ,
Corresponding angle for raw materials = 90°
Percent of total expenditure = 100%
Corresponding angle for total expenditure = 360°
we know that , 360° ≡ 100%

##### Correct Option: A

On the basis of given pie chart in question ,
Corresponding angle for raw materials = 90°
Percent of total expenditure = 100%
Corresponding angle for total expenditure = 360°
we know that , 360° ≡ 100%

 ∴ Required percent = 90° ≡ 100 × 90 = 25% 360

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. Royalty on the book is less than the printing cost by :

1. According to given pie chart in question ,
Percent of royalty cost = 20%
Percent of printing cost = 15%
Change in cost = 20 - 15 = 5%

 Required percent = Change in cost × 100 % Percent of royalty cost

##### Correct Option: C

According to given pie chart in question ,
Percent of royalty cost = 20%
Percent of printing cost = 15%
Change in cost = 20 - 15 = 5%

 Required percent = Change in cost × 100 % Percent of royalty cost

 Required percent = 20 - 15 × 100 % 20

 Required percent = 5 × 100 % = 25% 20

Direction: The following pie–chart shows the monthly expenditure of a family on various items. If the family spends \$ 825 on clothing, answer the questions.

1. What is the total monthly income of the family?

1. On the basis of given pie chart in question ,
Given that , Expenditure on clothes = Rs. 825.
The corresponding angle of total expenditure = 360°
The corresponding angle of expenditure on clothes = 36°
∵ 36° ≡ \$ 825

 ∴ Total monthly income = Expenditure on clothes × The corresponding angle of total expenditure The corresponding angle of expenditure on clothes

##### Correct Option: B

On the basis of given pie chart in question ,
Given that , Expenditure on clothes = Rs. 825.
The corresponding angle of total expenditure = 360°
The corresponding angle of expenditure on clothes = 36°
∵ 36° ≡ \$ 825

 ∴ Total monthly income = Expenditure on clothes × The corresponding angle of total expenditure The corresponding angle of expenditure on clothes

 ∴ Total monthly income = 825 × 360 = & 8250 36

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 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
