Explanation

Step 1: U sits on odd numbered floor but not above the floor number 6 and lkes black colour. There is a gap of one floor between U and both of the vacant floors. Neither P nor Q is an immediate neighbor of both vacant floors and they does not like Yellow and pink colour. so there should be two possibilities.
Case 1:
Case 2:
Step 2: Neither P nor Q is an immediate neighbor of vacant floor and they does not like yellow and pink colour. the person who likes grey colour stay on the 2nd floor. Q stays on an odd numbered floor which is above P. there is one floor between P and R who likes green colour.
Case 1:
Case 2:
From this statement Case -2 will be eliminated as in case -2- there are four floors between P and R.
Step 3: There are three floors between P and S who does not likes yellow colour. the person who likes brown colour stay on just above V.
