## Introduction to Data Interpretation

#### Data Interpretation

Direction: In the following questions, the pie-chart shows the number of students admitted in different faculties of a college.
Study the chart and answer the questions.

1. How many students are more in commerce than in law if 1000 students are in science?

1. Difference between the students of commerce and science = 200
[∵ 100° &rquvi; 1000
∴ 1° ≡ 10
∴ 20° ≡ 200]

##### Correct Option: A

Difference between the students of commerce and science = 200
[∵ 100° &rquvi; 1000
∴ 1° ≡ 10
∴ 20° ≡ 200]

Direction: The pie- chart given below represents the number of students using different transport to a school in which total number of students is 2160. Answer the questions based on the following diagram.

1. The number of students coming to school by bus exceeds the number of students coming to school walking, by

1. (Bus – Walking)%

 = 90 - 80 × 100 = 12.5% 80

##### Correct Option: B

(Bus – Walking)%

 = 90 - 80 × 100 = 12.5% 80

1. The number of students who don’t come to school by train is

1. No. of students do not come by train

 = 360 - 120 × 2160 = 1440 360

##### Correct Option: D

No. of students do not come by train

 = 360 - 120 × 2160 = 1440 360

1. The total number of students coming to school either by walking or by bus is

1. No. of students coming by (bus + walking)

 = 80 + 90 × 2160 = 1020 360

##### Correct Option: C

No. of students coming by (bus + walking)

 = 80 + 90 × 2160 = 1020 360

1. The ratio of the number of students who come to school by car to the number of students who come to school by bus is

1. Car : Bus = 70° : 90°
= 7 : 9 or 21 : 27

##### Correct Option: B

Car : Bus = 70° : 90°
= 7 : 9 or 21 : 27
