  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








  1. View Hint View Answer Discuss in Forum

    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

  1. The total number of products of electronic items is maximum in the year








  1. View Hint View Answer Discuss in Forum

    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 .

  1. The approximate percentage increase in quantity from 1997 to 1998 was










  1. View Hint View Answer Discuss in Forum

    From the given bar diagram , we see
    Quantity of sugar bags in 1997 = 130 lakhs
    Quantity of sugar bags in 1998 = 150 lakhs
    Increase in quantity = 150 - 130 = 20 lakhs

    Percentage increase =
    Increase in quantity
    		 × 100
    Quantity of sugar bags in 1997

    Percentage increase =
    20
    		 × 100
    130

    Correct Option: E

    From the given bar diagram , we see
    Quantity of sugar bags in 1997 = 130 lakhs
    Quantity of sugar bags in 1998 = 150 lakhs
    Increase in quantity = 150 - 130 = 20 lakhs

    Percentage increase =
    Increase in quantity
    		 × 100
    Quantity of sugar bags in 1997

    Percentage increase =
    20
    		 × 100
    130

    Percentage increase =
