    From the given bar diagram , we see
    The sales in 2003 = $ 420 × 1000
    The sales in 2001 = $ 320 × 1000
    Required difference = The sales in 2003 - The sales in 2001

    Correct Option: B

    From the given bar diagram , we see
    The sales in 2003 = $ 420 × 1000

    On the basis of given graph in question ,
    The sale in year 2000 = 340
    The sale in year 2001 = 320
    Decrease = The sale in year 2000 - The sale in year 2001 = 340 - 320 = 20

    Percentage decrease(2001) =
    Decrease
    × 100
    The sale in year 2000

    Percentage decrease(2001) =
    20
    × 100 = 6%
    340

    The sale in year 2004 = 440
    The sale in year 2005 = 400
    Decrease = The sale in year 2004 - The sale in year 2005 = 440 - 400 = 40
    Percentage decrease(2005) =
    Decrease
    × 100
    The sale in year 2004

    Correct Option: C

    On the basis of given graph in question ,
    The sale in year 2000 = 340
    The sale in year 2001 = 320
    Decrease = The sale in year 2000 - The sale in year 2001 = 340 - 320 = 20

    Percentage decrease(2001) =
    Decrease
    × 100
    The sale in year 2000

    Percentage decrease(2001) =
    20
    × 100 = 6%
    340

    The sale in year 2004 = 440
    The sale in year 2005 = 400
    Decrease = The sale in year 2004 - The sale in year 2005 = 440 - 400 = 40
    Percentage decrease(2005) =
    Decrease
    × 100
    The sale in year 2004

    Percentage decrease (2005) =
    40
    × 100 = 9%
