Best way to invest 10 Lakhs, but just for the next 3 months?

Hi all,

I have around 10 Lakhs as cash and would like to invest it temporarily for the next 3 months.

I plan to purchase a land but the registration would be after 3 to 5 months only! Thats why the temporary investment.

I’m a returned NRI; have no idea about mutual fund and Indian stocks! Please advise.
I’m ready for taking moderate risk!
