Hi, Raju. This is a problem in recriational mathematics. The solution is very simple. Let the right path be R and the wrong path be W. Let the two people be A and B. Where A always tells the truth and B always tells the false. So if you ask A "What do you think B would say is the right path?" A knows that the right path is R but since B is a lier, so B would always say W. For these reason A would always say W. However, if you ask B the same question, by the same deduction principle, B would say W.

So, if you want to find the right path you do the opposite of both and follow path R.
