## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie chart shows how the school funds is spent under different heads in a certain school. Using the pie chart answer the questions. 1. What is the ratio of expenditure on sports to that on art and craft?

1. As per the given pie chart in question ,
The corresponding angle of expense on sports = 120°
The corresponding angle of expense on art and craft = 90°
Required ratio = The corresponding angle of expense on sports : The corresponding angle of expense on art and craft

##### Correct Option: B

As per the given pie chart in question ,
The corresponding angle of expense on sports = 120°
The corresponding angle of expense on art and craft = 90°
Required ratio = The corresponding angle of expense on sports : The corresponding angle of expense on art and craft
Required ratio = 120° : 90°= 4 : 3

1. Which head has the maximum expenditure?

1. According to given pie chart in question ,
The corresponding angle of expense on sports = 120°.

##### Correct Option: B

According to given pie chart in question ,
The corresponding angle of expense on sports = 120°.Hence , sports has the maximum expenditure .

1. Which heads have the same amount of expenditure?

1. On the basis of given pie chart in question ,
The corresponding angle of expense on library = 60°
The corresponding angle of expense on science = 60°

##### Correct Option: A

On the basis of given pie chart in question ,
The corresponding angle of expense on library = 60°
The corresponding angle of expense on science = 60°
Hence , Library and Science have the same amount of expenditure .

1. Which head uses 25% of the funds?

1. As we know that , 100% ≡ 360°

 ∴ 1% ≡ 360 100

 ∴ 25% ≡ 360 × 25 = 90° 100

##### Correct Option: D

As we know that , 100% ≡ 360°

 ∴ 1% ≡ 360 100

 ∴ 25% ≡ 360 × 25 = 90° 100

Angle of Art and Craft = 90°
From given pie chart in question it is clear that Art and Craft uses 25% of the funds.

1. What percentage of the total expense is spent on the library?

1. As per the given in pie chart ,
The corresponding angle of expenditure on library = 60°
Total expenditure = 360°

 ∴ Required percent = The corresponding angle of expenditure on library × 100 Total expenditure

 ∴ Required percent = 60 × 100 360

##### Correct Option: D

As per the given in pie chart ,
The corresponding angle of expenditure on library = 60°
Total expenditure = 360°

 ∴ Required percent = The corresponding angle of expenditure on library × 100 Total expenditure

 ∴ Required percent = 60 × 100 360

 Required percent = 50 = 16.67% 3
