As per the given above bar diagram , we see that one box represents the number of 20.
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
Number of accidents involving buses = 120
Number of accidents involving tanker lorry = 160
Difference = 160 - 120 = 40Correct Option: B

Number of accidents involving tanker lorry = 160
Difference = 160 - 120 = 40Required percentage = 40 × 100 = 4% 1000
- The percentage of accidents in which pedestrians and cyclists are involved is

According to given bar diagram , we have
Number of accidents involving pedestrians and cyclists = 40 + 200 = 240
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000Required percentage = Number of accidents involving pedestrians and cyclists × 100 Total accidents
Correct Option: A
According to given bar diagram , we have
Number of accidents involving pedestrians and cyclists = 40 + 200 = 240
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000Required percentage = Number of accidents involving pedestrians and cyclists × 100 Total accidents Required percentage = 240 × 100 = 24% 1000

On the basis of given the bar diagram is represented by a pie-chart in question ,
Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
Total corresponding angle of pie chart = 360°
∵ 1000 ≈ 360 °Correct Option: D

∴ Required difference = Percentage of accidents involving two-wheelers and other objects - Percentage of accidents involving two-wheelers and two wheelers
Required difference = 77 – 23 = 54%
