India at 8% growth can double economy in 7-8 years, says NITI VC

India can double its economy in about 7-8 years if it grows at 8 per cent, which is feasible as the country has sustained a growth rate of 8.5 per cent earlier for a long time, Niti Aayog Vice-Chairman Rajiv Kumar said on Saturday. He said that the target of becoming a USD 5-trillion economy is not rhetoric, adding that the country is already a USD 2.7 trillion economy and it just needs to double it.
