## Introduction to Data Interpretation

#### Data Interpretation

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

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

1. Number of students who come to school by car.

 = 70 × 2160 = 420 360

##### Correct Option: C

Number of students who come to school by car.

 = 70 × 2160 = 420 360
