New Delhi: India's economic growth will rebound from a five-year low this year, but would need a huge boost in spending and reforms to accelerate higher rate of expansion to double the economy's size to USD 5 trillion by 2024-25, the pre-Budget Economic Survey said Thursday.

Stepping up private investments, exports and job creation will be key to achieving the target, the survey presented in Parliament by Finance Minister Nirmala Sitharaman said.
