Hi all
Position tolerance is an indirect control of perpendicularity but if i add refinement by giving perpendicularity tolerance then will it give some more tolerance on location????

No

No, by refining perpendicularity you don't implicitly increase the locational tolerance - it's 'refining' the looser perpendicularity you already get from your position control.

The key word is "refining" - you create new smaller tolerance zone inside of the larger tolerance zone.
