Direction: A bar graph showing the heights of six mountain peaks is given below. Study the bar graph and answer the questions.

  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 .

  1. The average height of all the peaks (in metre) is

    According to given bar graph , we have
    Total height of all the peaks = 8200 + 6000 + 8600 + 7500 + 8800 + 6500
    Number of mountain peaks = 6

    Required average height =
    Total height of all the peaks
    Number of mountain peaks

    Required average height =
    8200 + 6000 + 8600 + 7500 + 8800 + 6500
    6


    Correct Option: B

    According to given bar graph , we have
    Total height of all the peaks = 8200 + 6000 + 8600 + 7500 + 8800 + 6500
    Number of mountain peaks = 6

    Required average height =
    Total height of all the peaks
    Number of mountain peaks

    Required average height =
    8200 + 6000 + 8600 + 7500 + 8800 + 6500
    6

    Required average height =
    45600
    		 = 7600 metre

Direction: Study the bar diagram and answer the following questions. The bar diagram shows the number of bicycles parked in the parking space of a hall at various points of time.

  1. How many times, as mentioned in the graph, is the number of parked cycles above average?








  1. View Hint View Answer Discuss in Forum

    On the basis of given graph in question , we get
    The average = 60
    The number of parked cycles above average :

    Correct Option: D

    On the basis of given graph in question , we get
    The average = 60
    The number of parked cycles above average :
    Required answer = 6 times i.e., 95, 75, 85, 65, 75 and 65.

  1. What is the average number of parked cycles as seen from the graph?








  1. View Hint View Answer Discuss in Forum

    On the basis of given graph in question ,
    Number of cycles parked from 9 am to 8 pm.
    = 95 + 75 + 85 + 65 + 75 + 55 + 65 + 45 + 55 + 35 + 45 + 25 = 720
    Total time = 12 hours

    Required average =
    Number of cycles parked from 9 am to 8 pm
    		 =
    720
    Total time12

    Correct Option: D

    On the basis of given graph in question ,
    Number of cycles parked from 9 am to 8 pm.
    = 95 + 75 + 85 + 65 + 75 + 55 + 65 + 45 + 55 + 35 + 45 + 25 = 720
    Total time = 12 hours

    Required average =
    Number of cycles parked from 9 am to 8 pm
    		 =
    720
    		 = 60
    Total time12

  1. What is the percentage decrease in the number of parked cycles between 7 pm and 8 pm? (in whole number)








  1. View Hint View Answer Discuss in Forum

    As per the given bar graph ,
    The number of parked cycles at 7 pm
    = 45
    And The number of parked cycles at 8 pm = 25
    Decrease = 45 - 25 = 20

    Required percentage decrease = Decrease × 100
    The number of parked cycles at 7 pm

    Correct Option: D

    As per the given bar graph ,
    The number of parked cycles at 7 pm
    = 45
    And The number of parked cycles at 8 pm = 25
    Decrease = 45 - 25 = 20

    Required percentage decrease = Decrease × 100
    The number of parked cycles at 7 pm

    Required percentage decrease =
    20 × 100
    		 = 44.44%
    45
