    On the basis of given graph in question ,
    Total production of the company B in given years = 72000 + 90000 + 100000 = 262000 = 262 thousands
    Number of given years = 3

    Required average production = Total production of the company B in given years
    Number of given years

    Correct Option: A

    On the basis of given graph in question ,
    Total production of the company B in given years = 72000 + 90000 + 100000 = 262000 = 262 thousands
    Number of given years = 3

    Required average production = Total production of the company B in given years
    Number of given years

    Required average production =
    262
    		 = 87.33 thousands

    From the given bar diagram , we see
    Production of buses by company A in 2009 = 64000
    Production of buses by company A in 2010 = 70000
    Increase in production = 70000 - 64000 = 6000

    Percentage increase ⇒
    Increase in production
    		 × 100
    Production of buses by company A

    Percentage increase in year 2010 ⇒
    6000
    		 × 100 ≈ 9.4
    64000

    Production of buses by company A in 2010 = 70000
    Production of buses by company A in 2011 = 77000
    Increase in production = 77000 - 70000 = 7000
    Percentage increase in year 2011 ⇒
    7000
    		 × 100 = 10
    70000

    Production of buses by company A in 2011 = 77000
    Production of buses by company A in 2012 = 85000
    Increase in production = 85000 - 77000 = 8000

    Correct Option: B

    From the given bar diagram , we see
    Production of buses by company A in 2009 = 64000
    Production of buses by company A in 2010 = 70000
    Increase in production = 70000 - 64000 = 6000

    Percentage increase ⇒
    Increase in production
    		 × 100
    Production of buses by company A

    Percentage increase in year 2010 ⇒
    6000
    		 × 100 ≈ 9.4
    64000

    Production of buses by company A in 2010 = 70000
    Production of buses by company A in 2011 = 77000
    Increase in production = 77000 - 70000 = 7000
    Percentage increase in year 2011 ⇒
    7000
    		 × 100 = 10
    70000

    Production of buses by company A in 2011 = 77000
    Production of buses by company A in 2012 = 85000
    Increase in production = 85000 - 77000 = 8000
    Percentage increase in year 2012 ⇒
    8000
    		 × 100 ≈ 10.4
    77000

    Production of buses by company A in 2012 = 85000
    Production of buses by company A in 2013 = 93000
    Increase in production = 93000 - 85000 = 8000
    Percentage increase in year 2013 ⇒
    8000
    		 × 100 ≈ 9.5
    85000

    Hence , correct answer is 2012 year .

Direction: Study the following bar–diagram and answer the questions.

  1. The total units consumption in the year 2013 during these 5 months, in respect of the same in the previous year has been










  1. View Hint View Answer Discuss in Forum

    According to given bar graph , we have
    Total consumption in 2012 = 2200 units
    Total consumption in 2013 = 2300 units
    Total Increase = 2300 - 2200 = 100 units

    Percentage increase = Total Increase × 100
    Total consumption in 2012

    Correct Option: E

    According to given bar graph , we have
    Total consumption in 2012 = 2200 units
    Total consumption in 2013 = 2300 units
    Total Increase = 2300 - 2200 = 100 units

    Percentage increase = Total Increase × 100
    Total consumption in 2012

    Percentage increase =
    100
    		× 100 =
    50
    		 = 4.5 %
    220011

  1. The maximum difference in the units consumption between these two years has been found in the month of








  1. View Hint View Answer Discuss in Forum

    From the given bar diagram , we see that
    In the month of July, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 600 – 550 = 50 units
    In the month of August, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 700 – 500 = 200 units.
    In the month of September, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 400 – 400 = 0 units.
    In the month of October, Difference = Electric consumption in 2013 - Electric consumption in 2012
    Difference = 350 – 300 = 50 units.

    Correct Option: D

    From the given bar diagram , we see that
    In the month of July, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 600 – 550 = 50 units
    In the month of August, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 700 – 500 = 200 units.
    In the month of September, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 400 – 400 = 0 units.
    In the month of October, Difference = Electric consumption in 2013 - Electric consumption in 2012
    Difference = 350 – 300 = 50 units.
    In the month of November, Difference = Electric consumption in 2012 - Electric consumption in 2013
    Difference = 500 – 200 = 300 units
    Hence , required month is November .
