The best and easiest way is to convert STEEM/SBD to another currency like ETH or Dash and find a place to convert it to INR. https://localbitcoins.com/country/IN could be a great place. https://uphold.com is another great place although I'm not sure if it supports India.

Hope it works out well for you :) You ill loose a little bit of value for Tx fees on BTC or other coins.
