The given bar graph shows the biscuit exports of India over a period of five years. Study the graph and answer the question that follow.

In which year, the percentage increase in exports was maximum from its preceding year:

2007

Lets solve one by one for each option. 

1. 2009

Export in 2008 = 400

Export in 2009 = 500

Percentage increase in exports from its preceding year in 2009 = \(\frac{500-400 }{400}\) × 100

= \(\frac{100 }{400}\) × 100

= 25%

2. 2006

There is decrease in export in 2006 comparative to 2005.

3. 2008

Export in 2007 = 400

Export in 2008 = 500

Percentage increase in exports from its preceding year in 2008 = \(\frac{500-400 }{400}\) × 100

= \(\frac{100 }{400}\) × 100 

= 25%

4. 2007

Export in 2006 = 75

Export in 2007 = 150

Percentage increase in exports from its preceding year in 2007 = \(\frac{150-75 }{75}\) × 100

= \(\frac{75 }{75}\) × 100

= 100%

So , Percentage increase in exports from its preceding year in 2007
