I meant to say when u type and open india.wnso.org then, wnso.wordpress.com should open. Like u can see http://www.blog.com.np is wordpress blog but has been hosted in another domain. I am not technically so literate and sorry for a bit absurd question but I hope that u understood.
It’s $10 a year payable via Paypal. You can purchase credits which are the same as cash at Dashboard -> Upgrades -> The Upper right of the page. Unfortunely the smallest amount of credits you can pick up is $15 but you can save those extra five for later.
Once you get that, tell your registar or the person who is setting up for domain for you to use the wordpress nameservers. Those are ns1.wordpress.com, ns2.wordpress.com, and ns3.wordpress.com. You need to get them to use all three.
Once you’ve done that, take a look at Dashboard -> Options -> Domains and give that a read to get your domain setup on this end.
