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. 60% of the accidents are involved due to








  1. View Hint View Answer Discuss in Forum

    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.

    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?

    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. View Hint View Answer Discuss in Forum

    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

  1. Which peak is the second highest?








  1. View Hint View Answer Discuss in Forum

    As per the given bar graph ,
    Height of mountain peak C = 8600 metre

    Correct Option: B

    As per the given bar graph ,
    Height of mountain peak C = 8600 metre
    Hence , the second highest peak is C .
