    ∴ average =sum of the total persons killed in industrial accidents and coal mines
    total number of years

    Correct Option: C

    Total number of persons killed in industrial accidents and coal mines in
    2006 = 1200 + 300 = 1500
    2007 = 900 + 150 = 1050
    2008 = 1100 + 200 = 1300
    2009 = 800 + 200 = 1000
    Total number of persons killed
    = 1500 + 1050 + 1300 + 1000 = 4850

    ∴ average =sum of the total number of persons killed in industrial accidents and coal mines
    total number of years

    = 4850 = 1212.5
