## Introduction to Data Interpretation

#### Data Interpretation

Direction: The follow- ing pie-chart shows the number of students who failed in different subjects in an examination. Examine the chart and answer the following questions. The total number of students who have failed is 500.

1. The number of students failed in science is less than the number of students failed in all other subjects by :

1. Difference in percentage = (68 – 32)% = (36)%

 = 36 × 500 = 180 100

##### Correct Option: C

Difference in percentage = (68 – 32)% = (36)%

 = 36 × 500 = 180 100

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
