I had withdrawn Rs. 5 lacs from my GPF & now i intent to invest it some where else. suggest for more earning?

I have withdrawn Rs. 5 lac from my GPF account for purchase of house. But same could not be materialised due to some reasons. Now i want this amount be re-invested in some schemes, so that firstly i could get monthly income, good interest rates on these amounts. I also want to invest in mutual funds but do not know much about it. Please suggest.
