In the 'Index of Eight Core Industries', which one of the following is given the highest weight?

  1. (a) Coal production
  2. (b) Electricity generation ✓ UPSC's answer
  3. (c) Fertilizer production
  4. (d) Steel production

Why the answer is (b)

• The Index of Eight Core Industries (base 2011–12) has weights: refinery products 28.0%, electricity 19.9%, steel 17.9%, coal 10.3%, crude oil 9.0%, natural gas 6.9%, cement 5.4%, fertilisers 2.6%.

• Among the four options, electricity generation carries the highest weight — option (b); refinery products, the overall highest, is not offered.

• The eight core industries make up about 40% of the Index of Industrial Production.

• Hence option (b).

Why the other options are wrong

(a) Coal production
Coal has about 10% weight, lower than electricity.
(c) Fertilizer production
Fertilisers have the lowest weight (2.6%).
(d) Steel production
Steel (17.9%) is below electricity (19.9%).
