Six chairs labelled J, K, P, R, S and T are kept one above the other (not necessarily in the same order). R is above only P and S. There are four chairs between J and S. K is three places above P. If we arrange these chairs in alphabetical order from top to bottom, then the position of how many chairs (excluding J) will be changed?
