    On the basis of given graph in question ,
    The production of company Y in 2002 = 350 (in 1000 tonnes )
    The production of company Y in 2003 = 450 (in 1000 tonnes )
    Increase = 450 - 350 = 100 (in 1000 tonnes )

    Required percentage increase =

    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
