## Introduction to Data Interpretation

#### Data Interpretation

Direction: The pie- chart, given here, shows the land distribution of a village.
Study the pie-chart and answer the questions based on it. 1. The land used for roads is what per cent of the inhabited land?

1. Required percentage

 = 20 × 100 = 100 = 33 1 % 60 3 3

##### Correct Option: C

Required percentage

 = 20 × 100 = 100 = 33 1 % 60 3 3

1. If the total area of the village is 7200 acres, the total area of the wetland is

1. ∵ 360° 7200 acres

 ∴ 1° ≡ 7200 = 20 acres 360

∴ 70° ≡ 70 × 20 = 1400 acres

##### Correct Option: D

∵ 360° 7200 acres

 ∴ 1° ≡ 7200 = 20 acres 360

∴ 70° ≡ 70 × 20 = 1400 acres

1. What per cent of total land is used for cultivation?

1. ∵ 360° ≡ 100%

 ∴ I° ≡ 100 360

 ∴ 90° ≡ 100 × 90 = 25% 360

##### Correct Option: B

∵ 360° ≡ 100%

 ∴ I° ≡ 100 360

 ∴ 90° ≡ 100 × 90 = 25% 360

1. The ratio of the wasteland to the cultivated land is

1. Required ratio = 120° : 90° = 4 : 3

##### Correct Option: A

Required ratio = 120° : 90° = 4 : 3

Direction: The pie- chart, given here, shows various expenses of a publisher in the production and sale of a book. Study the chart and answer questions based on it. 1. The difference between the measure of central angles of sector for binding charges and advertisement charges is :

1. Central angle for binding charges

 = 360 × 18 = 64.8° 100

 = 360 × 18 = 64.8° 100

∴ Required difference = 0°
Method 2 :
Percentage value for both is same.
Therefore, difference between angles is same.

##### Correct Option: D

Central angle for binding charges

 = 360 × 18 = 64.8° 100
