For which of the following years is the percentage rise/fall in production from the previous year the maximum for Company Y?
1997

Correct answer is A
Percentage change (rise/fall) in the production of Company Y in comparison to the previous year, for different years are:
For 1997 = [ (35 - 25)/25 x 100 ] % = 40%
For 1998 = [ (35 - 35)/35 x 100 ] % = 0%
For 1999 = [ (40 - 35)/35 x 100 ] % = 14.29%
For 2000 = [ (50 - 40)/40 x 100 ] % = 25%
Hence, the maximum percentage rise/fall in the production of Company Y is for 1997.
