The Indian economy is at a “take off” stage and is expected to be the world’s third largest by 2030 with GDP worth $10 trillion, Economic Affairs Secretary Subhash Chandra Garg has said. “Good days are ahead and lot of good work is happening in the economy. The economy is on a stage of take off where Indians can legitimately hold their heads high. Eight per cent growth is very much achievable. If we keep that, we can look forward to be an Indian economy of $10 trillion which would be the third largest economy in the world,” Garg said.
