The year in which production increased the lowest as compared to the previous year is

Production in the year :

2001-02 = 200

2002-03 = 400

2003-04 = 600

2004-05 = 900

2005-06 = 800

2006-07 = 1000

2007-08 = 1200

=> % increase in 2002-03 as compared to previous year = $$\frac{400-200}{200}$$ * 100

= 100%

=> % increase in 2003-04 as compared to previous year = $$\frac{600-400}{400}$$ * 100

= 50%

=> % increase in 2004-05 as compared to previous year = $$\frac{900-600}{600}$$ * 100

= 50%

=> In 2005-06, there is no % increase as compared to previous year.

=> % increase in 2006-07 as compared to previous year = $$\frac{1000-800}{800}$$ * 100

= 25%

=> % increase in 2007-08 as compared to previous year = $$\frac{1200-1000}{1000}$$ * 100

= 20% [MIN]

Thus, % increase is lowest in 2007-08 as compared to previous year
