What does this dimension 3mm mean? I assume that it is starting from the line where 69mm dimension ends. I wish to know whether it is proper way of dimensioning.

Not sure where you're getting your examples from Maha, but they're not of a very high standard and may be teaching you a lot of bad practises.
Bjorn Hulman - couldn't have said it better - www.solidprofessor.com is what I would recommend if you can afford it...
69 and 3 both go to the center of the outside diameter, the 3 is the distance between the centers of the hole and the outside diameter.
ugly "print"
It is from the same point where 69mm ends, basically end of the linear line and start of the dia 30mm.
I completely agree with Bjorn that this is not correct way to dimension.
Looks like centre of diameter 10mm circle is 3mm up from centre of diameter 30 circle
