    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 = 40

    Correct Option: B

    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 = 40

    Required percentage =
    40
    		 × 100 = 4%
    1000

  1. 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 = 1000

    Required 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 = 1000

    Required percentage =
    Number of accidents involving pedestrians and cyclists
    		× 100
    Total accidents

    Required percentage =
    240 × 100
    		 = 24%
    1000

  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

    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

    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 °

    ∴ 100 ≡
    360
    		 × 100 = 36 °
    1000

    Therefore , required answer is stationary vehicles .

  1. 60% of the accidents are involved due to

    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
    Two-wheelers + Cars + Buses + Stationary Vehicles = 230 + 150 + 120 + 100 = 600

    Correct Option: C

    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
    Two-wheelers + Cars + Buses + Stationary Vehicles = 230 + 150 + 120 + 100 = 600

    Required percent =
    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.

    Total accidents = 230 + 150 + 120 + 160 + 40 + 200 + 100 = 1000
    Number of accidents involving two-wheelers and two-wheelers = 230
    Number of accidents involving two-wheelers and other objects = 770

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

    Correct Option: D

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