    According to given bar graph , we have
    FDI in 1992 = $ 5.7 billion
    FDI in 1993 = $ 10.15 billion
    Sum of FDI of 1992 and 1993 = FDI in 1992 + FDI in 1993

    Correct Option: B

    According to given bar graph , we have
    FDI in 1992 = $ 5.7 billion
    FDI in 1993 = $ 10.15 billion
    Sum of FDI of 1992 and 1993 = FDI in 1992 + FDI in 1993 = $ (5.7 + 10.15) billion = $ 15.85 billion.
    The sum of FDI of 1992 and 1993 is $ 15.85 billion.

    On the basis of given graph in question ,
    The production of fertilizer in year 1997 = 60
    The production of fertilizer in year 1998 = 45
    Decrease = 60 - 45 = 15

    Required percentage decrease =
    Decrease

    From the given bar diagram , we see
    The production of fertilizers in 1997 = 60 ( in tonnes )
    The production of fertilizers in 1996 = 40 ( in tonnes )
    Increase = The production of fertilizers in 1997 - The production of fertilizers in 1996 = 60 - 40 = 20

    Percentage increase in 1997 =
    20
    		 × 100 = 50%
    40

    The production of fertilizers in 1995 = 25 ( in tonnes )
    The production of fertilizers in 1996 = 40 ( in tonnes )
    Increase = The production of fertilizers in 1996 - The production of fertilizers in 1995 = 40 - 25 = 15

    Correct Option: B

    From the given bar diagram , we see
    The production of fertilizers in 1997 = 60 ( in tonnes )
    The production of fertilizers in 1996 = 40 ( in tonnes )
    Increase = The production of fertilizers in 1997 - The production of fertilizers in 1996 = 60 - 40 = 20

    Percentage increase in 1997 =

    40

    The production of fertilizers in 1995 = 25 ( in tonnes )
    The production of fertilizers in 1996 = 40 ( in tonnes )
    Increase = The production of fertilizers in 1996 - The production of fertilizers in 1995 = 40 - 25 = 15
    Percentage increase in 1996 =
    Increase

    According to given bar graph , we have
    The production of fertilizers in 2002 = 80
    The production of fertilizers in 1995 = 25
    Increase = 80 - 25 = 55

    Required percentage increase = Increase × 100
    The production of fertilizers in 1995

    Correct Option: A

    According to given bar graph , we have
    The production of fertilizers in 2002 = 80
