## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie- chart given below shows the usage of materials in the construction of a house. Study the chart and answers the questions : 1. If the cost of cement is \$ 5000, then the labour cost is :

1. From the given pie chart in question ,
The cost of cement = \$ 5000
Corresponding angle for cement = 72°
Corresponding angle for labour expenses = 90°
∵ 72° ≡ \$ 5000

 ∴ 1° = 5000 72

##### Correct Option: B

From the given pie chart in question ,
The cost of cement = \$ 5000
Corresponding angle for cement = 72°
Corresponding angle for labour expenses = 90°
∵ 72° ≡ \$ 5000

 ∴ 1° = 5000 72

 ∴ 90% ≡ \$ 5000 × 90° = \$ 6250 72°

1. The ratio of cement and bricks used in the construction is :

1. As per the given pie chart in question ,
The corresponding angle for cement = 72°
The corresponding angle for bricks = 54°
Required ratio = The corresponding angle for cement : The corresponding angle for bricks

##### Correct Option: C

As per the given pie chart in question ,
The corresponding angle for cement = 72°
The corresponding angle for bricks = 54°
Required ratio = The corresponding angle for cement : The corresponding angle for bricks
Required ratio = 72° : 54° = 4 : 3

1. The percentage of steel used in the construction of the house is

1. On the basis of given pie chart in question ,
Corresponding angle for steel = 36°
∵ 360° ≡ 100%

 ∴ 1% = 100 360

##### Correct Option: A

On the basis of given pie chart in question ,
Corresponding angle for steel = 36°
∵ 360° ≡ 100%

 ∴ 1% = 100 360

 ∴ 36% ≡ \$ 100 × 36° % = 10% 360

Direction: Study the pie-chart and answer the questions. The pie-chart given below shows the expenditure incurred in bringing out a book by a publisher. 1. If miscellaneous expenditures amount to \$ 12000, the expenditure on canvassing will be

1. According to given pie chart in question ,
Miscellaneous expenditures amount = \$ 12000
Percent of expenditure on miscellaneous = 2%
∵ 2% ≡ \$ 12000

 ∴ 1% = 12000 2

##### Correct Option: B

According to given pie chart in question ,
Miscellaneous expenditures amount = \$ 12000
Percent of expenditure on miscellaneous = 2%
∵ 2% ≡ \$ 12000

 ∴ 1% = 12000 2

 ∴ 24% ≡ \$ 12000 × 24 2

Expenditure on canvassing = \$ 144000

1. Royalty on the book is less than canvassing expenditure by

1. As per the given pie chart in question ,
Percent expenditure on Royalty = 24%
Percent expenditure on canvassing = 12%
Change in expenditure = 24 - 12 = 12%

 Required percent = Change in expenditure × 100 Percent expenditure on Royalty

##### Correct Option: B

As per the given pie chart in question ,
Percent expenditure on Royalty = 24%
Percent expenditure on canvassing = 12%
Change in expenditure = 24 - 12 = 12%

 Required percent = Change in expenditure × 100 Percent expenditure on Royalty

 Required percent = 12 × 100 = 50% 24
