Who amongst the following is an immediate neighbour of

Solution

O sits exactly in the centre of the row and faces the one who likes White. Only one person sits between V and the one who likes White. So V can be either extreme right or extreme left end of the row. So here we get following two cases: (1) When V sits extreme right end of the row   V faces one of the immediate neighbours of the one who likes Black. Only two people sit between M and the one who likes Black. M faces the one who likes Brown. P is an immediate neighbour of Q. So only two places left for P and Q. so U can be either at 2^nd or 3^rd to the right of the 2^nd row.   Now we know that S is not an immediate neighbour of U and faces the one who likes Red. U does not like Brown. S does not sit at the extreme end of the line. It means S sits 2^nd to the left end of the 2^nd row. So U sits 2^nd to the right end of the 2^nd row. U faces immediate neighbours of Q. so Q sits left end of the 1^st row. R faces the one who likes Violet. R does not like White. So R sits left end of the row and T sits at the centre of the row.    The one who likes Pink sits to the immediate right of the person who likes Orange. V does not like Pink. So this case is not valid. (2) When V sits extreme right end of the row V faces one of the immediate neighbours of the one who likes Black. Only two people sit between M and the one who likes Black. M faces the one who likes Brown. P is an immediate neighbour of Q. So only two places left for P and Q. so U can be either at 2^nd or 3^rd to the left end of the 2^nd row. Now we know that S is not an immediate neighbour of U and faces the one who likes Red. U does not like Brown. S does not sit at the extreme end of the line. It means S sits 2^nd to the right end of the 2^nd row. So U sits 2^nd to the left end of the 2^nd row. U faces immediate neighbours of Q. so Q sits right end of the 1^st row. R faces the one who likes Violet. R does not like White. So R sits right end of the row and T sits at the centre of the row.  The one who likes Pink sits to the immediate right of the person who likes Orange. V does not like Pink. The one who likes Green sits opposite to the person who sits left of the person who likes Pink. The one who likes Cream faces north.
