First of all thanks for your reply.
I have heard that BTCXIndia is closing down since one of it's banking partner has removed there support. So I am a bit skeptical about using that. Also is it possible to transfer LTC/XRP in any available wallet in India based exchange ?
There are no India based exchanges that provide LTC & XRP wallets that I know of. However they do provide directly converting your alt coins to bitcoins. Unocoin is one such exchange, you would still sell them in deficit if you aren't willing to the poloniex way.
