Just follow the ramadan wherever you are with full faith and strictly, India and Qatar are two different countries with thousands of kilometre apart, so there may be chagnes.

regarding layalatul qadr, it is not certain that it should be on 27th eve it can be any day after 20th of day of fasting, so one can assure it, just pray continuously after 20th day of fating during night with full faith you may get rewarded equally.
