@geriungurean If your risk appetite is zero, then put the money in FDs. That too in major banks, and not in small finance banks. (even though your money might be ensured up to 5 lacs in all banks, it's not the same as just clicking 3 buttons and getting your money, if a small bank goes bankrupt)
That's all you can do. And yes, that means, you cannot reach your goal with 0 risk.
Any other investment comes with risks.
You need around 16-17% XIRR returns over 2 years, to turn 3 lacs into 4 lacs. And that isn't possible without risks.
