    On the basis of given graph in question ,
    Sales in year 1994 = 400
    Capital in year 1994 = 200
    Sales : capital in 1994 → 2 : 1,
    Sales in year 1995 = 500
    Capital in year 1995 = 200
    Sales : capital in 1995 → 5 : 2,
    Sales in year 1996 = 300
    Capital in year 1996 = 200
    Sales : capital in 1996 → 3 : 2,
    Sales in year 1997 = 500
    Capital in year 1997 = 300
    Sales : capital in 1997 → 5 : 3,
    Sales in year 1998 = 800
    Capital in year 1998 = 300
    Sales : capital in 1998 → 8 : 3

    Correct Option: C

    On the basis of given graph in question ,

    According to given bar graph , we have
    Total increase in sales from 1994 to 1998 = 100 - 200 + 200 + 300 = 400
    Number of years = 5

    Required average =
    Total increase in sales from 1994 to 1998
    Number of years

    Correct Option: C

    According to given bar graph , we have
    Total increase in sales from 1994 to 1998 = 100 - 200 + 200 + 300 = 400
    Number of years = 5

    Required average =
    Total increase in sales from 1994 to 1998
    Number of years

    Required average =
    100 - 200 + 200 + 300
    		= $ 80 billion
