Solution (By Examveda Team)
$$\eqalign{ & \text{Chemical %} \cr & = \frac{986.4 - 745.3}{745.3} \times 100 \cr & = \frac{241.1 \times 100}{745.3} \cr & = 32.34\% \cr & \cr & \text{Solar %} \cr & = \frac{1792.1 - 1363.5}{1363.5} \times 100 \cr & = \frac{428.6}{1363.5} \times 100 \cr & = 31.4\% \cr & \cr & \text{Electricity %} \cr & = \frac{2365.1 - 2065.8}{2065.8} \times 100 \cr & = \frac{299.3}{2064.8} \times 100 \cr & = 14.4\% \cr & \cr & \text{Nuclear %} \cr & = \frac{2182.1 - 1674.3}{1674.3} \times 100 \cr & = \frac{507.8}{1674.3} \times 100 \cr & = 30.3\% \cr} $$So the highest percentage is in Chemical area
