    From the given bar diagram , we see
    Total production of Company X = 300 + 450 + 250 + 500 + 400 = 1900
    Number of years = 5

    Average production of Company X =
    Total production of Company X
    Number of years

    Average production of Company X =
    1900
    		= 380 thousand tonnes
    5

    Total production of Company Y = 250 + 350 + 350 + 400 + 500 = 1850
    Number of years = 5
    Average production of Company Y =
    Total production of Company Y
    Number of years

    Average production of Company Y =
    1800
    		= 370 thousand tonnes
    5

    Total production of Company Z = 350 + 400 + 450 + 350 + 350 = 1900
    Number of years = 5
    Average production
    of Company Z =
    Total production of Company Z
    Number of years

    Correct Option: A

    From the given bar diagram , we see
    Total production of Company X = 300 + 450 + 250 + 500 + 400 = 1900
    Number of years = 5

    Average production of Company X =
    Total production of Company X
    Number of years

    Average production of Company X =
    1900
    		= 380 thousand tonnes
    5

    Total production of Company Y = 250 + 350 + 350 + 400 + 500 = 1850
    Number of years = 5
    Average production of Company Y =
    Total production of Company Y
    Number of years

    Average production of Company Y =
    1800
    		= 370 thousand tonnes
    5

    Total production of Company Z = 350 + 400 + 450 + 350 + 350 = 1900
    Number of years = 5
    Average production
    of Company Z =
    Total production of Company Z
    Number of years

    Average production
    of Company Z =
    1900
    		= 380 thousand tonnes

    From the given bar diagram , we see
    Total production of company X in the period 2002-2004 = 250 + 500 + 400 = 1150
    Total production of company Y in the period 2002-2004 = 350 + 400 + 500 = 1250
    Number of given years = 3

    Required ratio = 250 + 500 + 400 : 350 + 400 + 500
    33

    Correct Option: C

    From the given bar diagram , we see
    Total production of company X in the period 2002-2004 = 250 + 500 + 400 = 1150
    Total production of company Y in the period 2002-2004 = 350 + 400 + 500 = 1250
    Number of given years = 3

    Required ratio = 250 + 500 + 400 : 350 + 400 + 500
    33

    Required ratio = 1150 : 1250 = 23 : 25

    From the given bar diagram , we see
    The production of cotton in state B in 2005- 2006 = 21 lakh
    The production of cotton in state B in 2005- 2006 = 7 lakh

    Correct Option: B

    From the given bar diagram , we see
    The production of cotton in state B in 2005- 2006 = 21 lakh
    The production of cotton in state B in 2005- 2006 = 7 lakh
    Hence , Required states are B and E.
