Study the given bar graph to answer the following question. The bar graph shows the length (in thousand kilometers) of mountains, forests and rivers in different states.

The length of mountains in Punjab is what percentage more than the length of rivers in Odisha?

300%

Length of mountains in Punjab = 40

Length of rivers in Odisha = 10 

Required percentage = \(\frac{40 - 10 }{10}\) × 100

= \(\frac{30}{10}\) × 100 = 300%
