A. 1996
B. 1997
C. 1998
D. 1999
E. 2000

Answer: Option B

Explanation:

The percentage rise/fall in production from the previous year for flavour Y during various years are:

In 1996 =[(60 - 55)x 100]% = 9.09% (increase)
55

In 1997 =[(60 - 50)x 100]% = 16.67% (decrease)
60

In 1998 =[(55 - 50)x 100]% = 10% (increase)
55

In 1999 =[(55 - 50)x 100]% = 9.09% (decrease)
55

In 2000 =[(55 - 50)x 100]% = 10% (increase)
50

Therefore Maximum change is decrease of 16.67% during 1997.
