    According to given graph , we have
    Total number of selected employees by company A = 150 + 300 + 300 + 500 + 650 + 800 = 2700
    Number of given grades = 6

    Required average =
    Total number of selected employees by company A
    Number of given grades


    Correct Option: A

    According to given graph , we have
    Total number of selected employees by company A = 150 + 300 + 300 + 500 + 650 + 800 = 2700
    Number of given grades = 6

    Required average =
    Total number of selected employees by company A
    Number of given grades

    Required average =
    2700
    = 450
    6


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.

    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 .

    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.
