## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following is a horizontal bar diagram showing the accidents in which two-wheelers are involved with other objects. Study the diagram and answer the questions.

1. If the data of the bar diagram is represented by a pie-chart, and the angle of a sector of the pie- chart is 36°, then this sector represents the accidents involving

1. On the basis of given graph in question , we see that one box represents a number of 20 units.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 units
In pie chart , complete angle = 360°
∵ 1000 ≡ 360°

 ∴ 100 ≡ 360 × 100 = 36° 1000

##### Correct Option: D

On the basis of given graph in question , we see that one box represents a number of 20 units.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 units
In pie chart , complete angle = 360°
∵ 1000 ≡ 360°

 ∴ 100 ≡ 360 × 100 = 36° 1000

From above clear that this sector represents the accidents involving stationary vehicles .
So , stationary vehicles having in diagram = 5 Boxes = 5 × 20 = 100 units
Hence , required answer is option D .

1. 60% of the accidents are involved due to

1. According to given bar graph , we have
The accidents of ( Two-wheelers + Cars + Buses + Stationary Vehicles ) = 230 + 150 + 120 + 100 = 600 units
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 units

##### Correct Option: C

According to given bar graph , we have
The accidents of ( Two-wheelers + Cars + Buses + Stationary Vehicles ) = 230 + 150 + 120 + 100 = 600 units
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000 units

 Required percentage = 600 × 100 = 60% 1000

Hence , required answer is option C .

1. The difference in percentage between the accidents involving two-wheelers and two-wheelers and two-wheelers and other objects is respectively.

1. On the basis of given graph in question ,
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000

 Percentage of accidents involving two-wheelers and two wheelers = 230 × 100 = 23% 1000

 Percentage of accidents involving two-wheelers and other objects = 770 × 100 = 77% 1000

##### Correct Option: D

On the basis of given graph in question ,
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000

 Percentage of accidents involving two-wheelers and two wheelers = 230 × 100 = 23% 1000

 Percentage of accidents involving two-wheelers and other objects = 770 × 100 = 77% 1000

∴ Required difference = 77 – 23 = 54%

Direction: A bar graph showing the heights of six mountain peaks is given below. Study the bar graph and answer the questions.

1. When the heights of the given peaks are written in ascending order, what is the average of the middle two peaks?

1. From the given bar diagram , we see
The ascending order is : 6000 < 6500 < 7500 < 8200 < 8600 < 8800

 Required average = 7500 + 8200 2

##### Correct Option: D

From the given bar diagram , we see
The ascending order is : 6000 < 6500 < 7500 < 8200 < 8600 < 8800

 Required average = 7500 + 8200 2

 Required average = 15700 = 7850 metre 2

1. What is the respective ratio of the heights of the highest peak and the lowest peak?

1. According to given bar graph , we have
The heights of the highest peak = 8800
and The heights of the lowest peak = 6000
Required ratio = The heights of the highest peak : The heights of the lowest peak

##### Correct Option: A

According to given bar graph , we have
The heights of the highest peak = 8800
and The heights of the lowest peak = 6000
Required ratio = The heights of the highest peak : The heights of the lowest peak
Required ratio = 8800 : 6000 = 22 : 15
