I know that the answer to the question "What index measures the economical performance?" is in "The gross state domestic product (GSDP) of Delhi at current prices for the year 2011-12 has been estimated at Rs 3.13 lakh crore, which is an increase of 18.7 per cent over the previous fiscal.". Can you tell me what it is?
