In which year was there maximum percentage increase in export of pearls to that in the previous year?

Answer:

Explanation:

Increase % in various years:

2002 → $\left\{\frac{6.5-5.2}{5.2}\times100\right\}$%

= $\left(\frac{13}{52}\times100\right)$% = 25%

2003 → $\left\{\frac{7.8-6.5}{6.5}\times100\right\}$%

= $\left(\frac{13}{65}\times100\right)$ % = 20%

2004 → $\left\{\frac{9.9-7.8}{7.8}\times100\right\}$%

= $\left(\frac{21}{78}\times100\right)$ % = 26.9%

2005 → $\left\{\frac{10.8-9.9}{9.9}\times100\right\}$%

= $\left(\frac{9}{99}\times100\right)$% = 11.1%

2007 → $\left\{\frac{11.4-9.5}{9.5}\times100\right\}$ %

= $\left(\frac{19}{95}\times100\right)$% = 20%.

Clearly, the maximum increase was in 2004.
