What is mothly income scheme?

I want to know how monthly income schemes of mutual funds work, like if i invest 50000 rupees, how the money will be invested and how much return i can expect from this much capital and how long will this money be invested, i mean is there a time period. i dont know how this works so please any kind of guidance will be appreciated. i want a monthly income of rupees 5000 so how much i should invest and which MIS is the best. Also is there any training institute for people from non finance background which coaches the basics and working of the stock market. Thanks.
