At last at 10.17 IST I have done it

Well done, congratulations.
Some one even asked on forum if they were connected or not that's what I tried doing and it worked.

T'was I/
but one question arises in My mind if I have a 12V relay been driven by ULN then how can I connect the two grounds?
Ground is ground is ground is zero volts. Who cares. But watch out where you tie the common diode connection to the ULN IT MUST GO TO THE +12 V line !
Please do clarify my doubts

I think you mean resolve your doubts - your doubts are quite clear enough !
