Study the following bar graph and answer the question that follows.

In which year was the maximum percentage increase in diamond exports compared to the previous year?

2009

Lets solve one by one for each option .

1. 2010

Export of diamond in 2009 = 8.5

Export of diamond in 2010 = 9.8

Percentage increase in export of diamond in 2010 comparative to previous year

=  \(\frac{9.8 - 8.5  }{8.5 }\) × 100

= \(\frac{1.3  }{8.5 }\) × 100 

= 15.29%

2. 2012

Export of diamond in 2011 = 10.9

Export of diamond in 2012 = 9.8

Percentage increase in export of diamond in 2010 comparative to previous year

=  \(\frac{9.8 - 8.5  }{8.5 }\) × 100

= \(\frac{1.3  }{8.5 }\) × 100

= 1.76%

3. 2014

Export of diamond in 2013 = 11.5

Export of diamond in 2014 = 12.4

Percentage increase in export of diamond in 2010 comparative to previous year

=  \(\frac{12.4 - 11.5  }{11.5 }\) × 100

= \(\frac{0.9  }{11.5 }\) × 100

= 7.82%

4. 2009

Export of diamond in 2008 = 7.2

Export of diamond in 2009 = 8.5

Percentage increase in export of diamond in 2010 comparative to previous year

=  \(\frac{8.5 - 7.2  }{7.2 }\) × 100

= \(\frac{1.3  }{7.2 }\) × 100

= 18.05%

Maximum percentage increase in diamond exports compared to the previous year is in 2009.
