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??
