Hi lovely purva and welcome to hubpages. To answer your question there is no such thing as "easy money" here at hubpages. You have to write lots of great content and it might take 6+ months before your content "sinks in" and is found, and consequently starts earning you money.
Lots of us have done it, though, and once the money starts rolling in it snowballs and gets bigger and bigger :) It's up to you how seriously you want to work at it, but it is possible to earn enough money to reach google's payout threshold each month ($100).
Imagine getting a $100+ check monthly just for writing some articles? It's pretty sweet, let me tell you. (Oh and I make that, but not just with the hubs on this one account...I have several).
