Solution:
Percentage increase in China ​​$$= \left( \frac{1700 - 750}{750} \right) \times 100 = \left( \frac{950}{750} \right) \times 100 = 126.67\% \text{ (approx)}$$

Percentage increase in Russia  $$= \left( \frac{1800 - 900}{900} \right) \times 100 = \left( \frac{900}{900} \right) \times 100 = 100\%$$​​

Percentage increase in Japan  ​$$= \left( \frac{1500 - 700}{700} \right) \times 100 = \left( \frac{800}{700} \right) \times 100 = 114.28\% \text{ (approx)}$$
Percentage increase in Europe   $$= \left( \frac{1800 - 600}{600} \right) \times 100 = \left( \frac{1200}{600} \right) \times 100 = 200\%$$​​
India’s exports to Europe increased most in terms of percentage between 2000-01 and 2010 – 2011.
