## Introduction to Data Interpretation

#### Data Interpretation

Direction: The expenses of a country for a particular year is given in Pie–Chart. Read the Pie– Chart and answer the questions. 1. If the total amount spent by the Government during the year was \$ 1,00,000 crores, then the amount spent on Health and Education together was

1. ∵ 100% ≡ 360°

 ∴ 10% ≡ 360 × 10 = 36° 100

∴ Corresponding angle for expenditure on health and education
≡ 36 + 54 = 90°
∵ 360° ≡ \$ 100000 crores
 ∴ 90° ≡ 100000 × 90° 360

= \$ 25000 crores

##### Correct Option: A

∵ 100% ≡ 360°

 ∴ 10% ≡ 360 × 10 = 36° 100

∴ Corresponding angle for expenditure on health and education
≡ 36 + 54 = 90°
∵ 360° ≡ \$ 100000 crores
 ∴ 90° ≡ 100000 × 90° 360

= \$ 25000 crores

Direction: In an Institution there are 800 students. Students use different modes of transport for going to the institution and return. The given pie diagram represents the requisite data. Study the diagram carefully and answer the questions. 1. The number of students who go to institute on foot is

1. Corresponding angle to the number of students who go to institute on foot
= 360° – (216° + 54° + 18°) = 72°

 = 72 × 800 = 160 360

##### Correct Option: A

Corresponding angle to the number of students who go to institute on foot
= 360° – (216° + 54° + 18°) = 72°

 = 72 × 800 = 160 360

1. The number of students who do not use institute bus is

1. Corresponding angle to number of students who do not use institute bus = 360° – 216° = 144°
∵ 360° ≡ 800

 ∴ 144° ≡ 800 × 144° = 320 360

##### Correct Option: D

Corresponding angle to number of students who do not use institute bus = 360° – 216° = 144°
∵ 360° ≡ 800

 ∴ 144° ≡ 800 × 144° = 320 360

1. The number of students who travel in public bus is

1. Corresponding angle to the number of students who travel by public bus = 54°
∵ 360° ≡ 800

 ∴ 54° ≡ 800 × 54° = 120 360

##### Correct Option: B

Corresponding angle to the number of students who travel by public bus = 54°
∵ 360° ≡ 800

 ∴ 54° ≡ 800 × 54° = 120 360

Direction: The following graph represents the transport used by children. Study the graph and answer the given questions. 1. If 180 students come walking to school what is the strength of the school?

1. ∵ 144° ≡ 180 students

 ∴ 360° ≡ 180 × 360 144

= 450 students

##### Correct Option: B

∵ 144° ≡ 180 students

 ∴ 360° ≡ 180 × 360 144

= 450 students
