Can anyone explain me the solution of data interpretation test 4 of cat quotient

Hi Shankho,
The graphs in the question show the growth rate for different sectors. It is also given that what is the contribution of each sector to the overall growth. The questions are fairly straight forward and are either observation based or require some calculation. For example, if we take the first question, it simply asks which sector saw the highest overall growth. So if you look at the graph, we can see the electricity sector consistently has a good growth rate. So it must have the highest overall growth. If you have some doubt in understanding the graph, please let us know.
Thanks
