Development where pages or sub-domains are created does not add value to a domain at all. Besides, those subdomains you mentioned doesn't make sense with the domain name.
$0. Get a refund if possible.
With .in domains, it has to be a really good name for it to have value.
if you are an impatient domainer and cant wait to get rid of this name(via sale or other means) then your name is worth$0-$20. If you are willing to wait and enjoy this market with alot of potential, then you are looking at $xxx in several years(hopefully).
I've realized .in is a waiting game. if you can't wait and be patient get out. if you can, get to it and keep renewing your names. .IN will wipe out most ccTLDs in performance in the next decade.
