    As per the given bar graph , we see
    Total production in 1996 and 1997 = 40 + 60 = 100 ten thousand tonnes
    Total production in 1995 and 2001 = 25 + 75 = 100 ten thousand tonnes

    Correct Option: A

    As per the given bar graph , we see
    Total production in 1996 and 1997 = 40 + 60 = 100 ten thousand tonnes
    Total production in 1995 and 2001 = 25 + 75 = 100 ten thousand tonnes
    Hence , correct answer is option A .

    On the basis of given graph in question ,
    Sum of the production of fertilizers = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 440
    Number of given years = 8

    Average production =
    Sum of the production of fertilizers
    Number of given years

    Average production = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 ten thousand tonnes
    8

    Correct Option: A

    On the basis of given graph in question ,
    Sum of the production of fertilizers = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 = 440
    Number of given years = 8

    Average production =
    Sum of the production of fertilizers
    Number of given years

    Average production = 25 + 40 + 60 + 45 + 65 + 50 + 75 + 80 ten thousand tonnes
    8

    Average production =
    440
    = 55 ten thousand tonnes
    8

    Required years ⇒ 1997, 1999, 2001 and 2002
