Previous Year Question

The Index of Eight Core Industries—ICI measures changes in the production of eight major infrastructure industries.

When this question was asked in 2015, the applicable series had 2004-05 as its base year. Under that series, the eight core industries collectively carried a weight of 37.90% in the then Index of Industrial Production—IIP.

Their principal weights in the old IIP series were:

Electricity had the highest weight—10.32%—among all eight industries under that series. Therefore, option (b) is correct.

Important fact about the revised series

The base year was subsequently revised to 2011-12. Under the revised series, the combined weight of the eight core industries in IIP increased to 40.27%.

The revised weights within the ICI are:

Under the revised series, Petroleum Refinery Products have the highest overall weight. However, they are not among the options. Electricity continues to have the highest weight among the four industries listed in the question.

The ICI is compiled and released by the Office of Economic Adviser, DPIIT, Ministry of Commerce and Industry.
