Need advice on investing.

Hey guys, new investor[21] here. I work as a developer and earn pretty good for myself. I have saved nearly 1L so that I can start investing in mutual funds. Please advice this newbie in which sectors to invest and how much to allocate.

How much SIP would you recommend starting out with if I earn 1L+ in a month? My monthly expenses are less than 20k every month (rent, food, etc).
