Introduction to 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.
- 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

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

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 .
- 60% of the accidents are involved due to

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 unitsCorrect 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 unitsRequired percentage = 600 × 100 = 60% 1000
Hence , required answer is option C .
- The difference in percentage between the accidents involving two-wheelers and two-wheelers and two-wheelers and other objects is respectively.

From the given bar diagram , we see
The ascending order is : 6000 < 6500 < 7500 < 8200 < 8600 < 8800Required average = 7500 + 8200 2
Correct Option: D
From the given bar diagram , we see
The ascending order is : 6000 < 6500 < 7500 < 8200 < 8600 < 8800Required average = 7500 + 8200 2 Required average = 15700 = 7850 metre 2
- What is the respective ratio of the heights of the highest peak and the lowest peak?

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 peakCorrect 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
