## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following pie-chart shows the expenditure incurred on the construction of a house in a city.
Study the chart and answer the following questions. 1. Of the total expenditure, the percentage of expenditure on steel and bricks together is

1. Required percent

 = 36 + 54 × 100 = 25% 360

##### Correct Option: C

Required percent

 = 36 + 54 × 100 = 25% 360

1. What part of expenditure on labour is in respect of total expenditure?

1. ∵ 360° ≡ 1

 ∴ 90 ° ≡ 90 = 1 360 4

##### Correct Option: C

∵ 360° ≡ 1

 ∴ 90 ° ≡ 90 = 1 360 4

1. The highest expenditure in percentage is

1. ∵ 360° ≡ 100%

 ∴ 108 % ≡ 100 × 108 = 30% 360

##### Correct Option: B

∵ 360° ≡ 100%

 ∴ 108 % ≡ 100 × 108 = 30% 360

1. The ratio of expenditure on Steel, Cement and Bricks is

1. Required ratio
= 36 : 72 : 54
= 2 : 4 : 3

##### Correct Option: A

Required ratio
= 36 : 72 : 54
= 2 : 4 : 3

1. The mean of the expenditure is on

1. Corresponding angle of average expenditure

 = 360° = 72° ≡ cement 5

##### Correct Option: B

Corresponding angle of average expenditure

 = 360° = 72° ≡ cement 5
