mutual funds???

I am planning to invest in mutual funds around 50k, for a short term, might not extend beyond 3-4 months, that would yeild the most. I want to know which is the better one in india?? and would it be possible to know where the firm has been investing???? Please Help me.
When i checked the for past 3 years, i couldnt find any dip for the 3 month investments( correct me if i am wrong). I want to increase my money as much as possible in the shotest duration. SInce, I am new to this i would want to play safe and also. Would it be possible for you to let me know what are the other forms of safe investments. or which mutual fund to go for, i could see that the magnum global fund has yeilded 22% and principal tax savings has yeilded 18.5% do you think that these will continue to appriciate or are they saturated or which one might appreciate the most for the next 3 months.
and also what do you mean by money market fund??

How hard is it to get a job at the World Bank or IMF?

im a finance masters from the US and want to get into the public sector in development banking or projects. i realize that these 2 employers are the best for the kind of exp im looking for. however im also aware that they’re tough to get into, but just wondering how to start and what kind of competition i mite be facing. any info on how to get a foot in the door is appreciated, even an internship is fine at this pt. a chance is all i need…esp during these times.
