    From the given bar diagram , we see
    Production of flavour Q in 2007 = 50 lakh
    Production of flavour Q in 2006 = 60 lakh
    Decrease = Production of flavour Q in 2006 - Production of flavour Q in 2007 = 60 - 50 = 10

    In year 2007 , Decrease % =
    Decrease
    		 × 100
    Production of flavour Q in 2006

    Correct Option: A

    From the given bar diagram , we see
    Production of flavour Q in 2007 = 50 lakh
    Production of flavour Q in 2006 = 60 lakh
    Decrease = Production of flavour Q in 2006 - Production of flavour Q in 2007 = 60 - 50 = 10

    In year 2007 , Decrease % =
    Decrease
    		 × 100
    Production of flavour Q in 2006

    In year 2007 , Decrease % =

    From the given bar diagram , we see
    Total sales of branch B2 for both the years = 75 + 65 = 140
    Total sales of branch B4 for both the years = 85 + 95 = 180
    Required ratio = Total sales of branch B2 for both the years : Total sales of branch B4 for both the years

    Correct Option: D

    From the given bar diagram , we see
    Total sales of branch B2 for both the years = 75 + 65 = 140
    Total sales of branch B4 for both the years = 85 + 95 = 180
    Required ratio = Total sales of branch B2 for both the years : Total sales of branch B4 for both the years
    ∴ Required ratio = 140 : 180 = 7 : 9
