    According to given bar graph , we have
    Total number of runs of two innings who scored highest = 60 + 80 = 140
    Number of innings = 2

    Required average runs =
    Total number of runs of two innings who scored highest
    		=
    140
    Number of innings2

    Correct Option: A

    According to given bar graph , we have
    Total number of runs of two innings who scored highest = 60 + 80 = 140
    Number of innings = 2

    Required average runs =
    Total number of runs of two innings who scored highest
    		=
    140
    Number of innings2

    Required average runs = 70
    The required cricketer is Mahendra Singh Dhoni.

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

  1. The ratio of production of TVs in the years 2009 and 2010 is








  1. View Hint View Answer Discuss in Forum

    On the basis of given graph in question ,
    Number of production of TVs in the year 2009 = 6000
    Number of production of TVs in the year 2010 = 9000
    Required ratio = Number of production of TVs in the year 2009 : Number of production of TVs in the year 2010

    Correct Option: C

    On the basis of given graph in question ,
    Number of production of TVs in the year 2009 = 6000
    Number of production of TVs in the year 2010 = 9000
    Required ratio = Number of production of TVs in the year 2009 : Number of production of TVs in the year 2010
    Hence , Required ratio = 6000 : 9000 = 2 : 3

  1. The difference between averages of production of TVs and LCDs from 2009 to 2012 is

    From the given bar diagram , we see
    Total production of T.V. from 2009 to 2012 = 6000 + 9000 + 13000 + 11000 = 39000
    Number of given years = 4

    Average production of T.V. from 2009 to 2012 =
    Total production of T.V. from 2009 to 2012
    Number of given years

    Average production of T.V. from 2009 to 2012 =
    39000
    		 = 9750
    4

    Total production of L.C.D from 2009 to 2012 = 7000 + 9400 + 9000 + 10000 = 35400
    Number of given years = 4
    Average production of LCD from 2009 to 2012 =
    Total production of L.C.D from 2009 to 2012
    Number of given years

    Correct Option: D

    From the given bar diagram , we see
    Total production of T.V. from 2009 to 2012 = 6000 + 9000 + 13000 + 11000 = 39000
    Number of given years = 4

    Average production of T.V. from 2009 to 2012 =
    Total production of T.V. from 2009 to 2012
    Number of given years

    Average production of T.V. from 2009 to 2012 =
    39000
    		 = 9750
    4

    Total production of L.C.D from 2009 to 2012 = 7000 + 9400 + 9000 + 10000 = 35400
    Number of given years = 4
    Average production of LCD from 2009 to 2012 =
    Total production of L.C.D from 2009 to 2012
    Number of given years

    Average production of LCD from 2009 to 2012 =
    35400
    		 = 8850
    4

    Required difference = Average production of TV from 2009 to 2012 - Average production of LCD from 2009 to 2012
    ∴ Required difference = 9750 – 8850 = 900

  1. The ratio of production of LCDs in the year 2011 and 2013 is

    On the basis of given graph in question ,
    Number of production of LCDs in the year 2011 = 9000
    Number of production of LCDs in the year 2013 = 12000
    Required Ratio = Number of production of LCDs in the year 2011 : Number of production of LCDs in the year 2013

    Correct Option: A

    On the basis of given graph in question ,
    Number of production of LCDs in the year 2011 = 9000
    Number of production of LCDs in the year 2013 = 12000
    Required Ratio = Number of production of LCDs in the year 2011 : Number of production of LCDs in the year 2013
    ∴ Required Ratio = 9000 : 12000 = 3 : 4

    According to given bar graph , we have
    Total production of electronic items in year 2009 ⇒ 6000 + 7000 = 13000
    Total production of electronic items in year 2010 ⇒ 9000 + 9400 = 18400
    Total production of electronic items in year 2011 ⇒ 13000 + 9000 = 22000
    Total production of electronic items in year 2012 ⇒ 11000 + 10000 = 21000
    Total production of electronic items in year 2013 ⇒ 8000 + 12000 = 20000

    Correct Option: C

    According to given bar graph , we have
    Total production of electronic items in year 2009 ⇒ 6000 + 7000 = 13000
    Total production of electronic items in year 2010 ⇒ 9000 + 9400 = 18400
    Total production of electronic items in year 2011 ⇒ 13000 + 9000 = 22000
    Total production of electronic items in year 2012 ⇒ 11000 + 10000 = 21000
    Total production of electronic items in year 2013 ⇒ 8000 + 12000 = 20000
    Hence , The total number of products of electronic items is maximum in the year 2011 .
