Question
Which of the following pairs represent the people
sitting at extreme end of the rows? Read the information carefully and answer the given question . Ten people are sitting in two parallel rows, containing five people. In one row, A, B, C, D and E are seated and all of them are facing north and in second row, F, G, H, I and J are seated and all of them are facing south, not necessarily in the same order. Each person also likes a different Colour namely, Pink, Red, Green, Yellow, White, Black, Orange, Brown, Violet, Cream, not necessarily in the same order.  C sits exactly in the centre of the row and faces the one who likes White. J faces one of the immediate neighbours of the one who likes Black. The one who likes Yellow is not an immediate neighbour of J. G is not an immediate neighbour of I and faces the one who likes Red.  A faces the one who likes Brown. I faces immediate neighbours of E. I does not like Brown. D is an immediate neighbour of E. G does not sit at the extreme end of the line. The one who likes Cream faces north. Only one person sits between J and the one who likes White. The one who likes Pink sits to the immediate right of the person who likes Orange. J does not like Pink. F faces the one who likes Violet. F does not like White. Only two people sit between A and the one who likes Black. The one who likes Green sits opposite to the person who sits left of the person who likes Pink.       ÂSolution
C sits exactly in the centre of the row and faces the one who likes White. Only one person sits between J and the one who likes White. So J can be either extreme right or extreme left end of the row. So here we get following two cases: (1) When J sits extreme right end of the row. J faces one of the immediate neighbours of the one who likes Black. Only two people sit between A and the one who likes Black. A faces the one who likes Brown. D is an immediate neighbour of E. So only two places left for D and E. so I can be either at 2nd or 3rd to the right of the 2nd row.  Now we know that G is not an immediate neighbour of I and faces the one who likes Red. I does not like Brown. G does not sit at the extreme end of the line. It means G sits 2nd to the left end of the 2nd row. So I sits 2nd to the right end of the 2nd row. I faces immediate neighbours of E. so E sits left end of the 1st row. F faces the one who likes Violet. F does not like White. So F sits left end of the row and H sits at the centre of the row.  The one who likes Pink sits to the immediate right of the person who likes Orange. J does not like Pink. So this case is not valid. 
(2) When J sits extreme right end of the row J faces one of the immediate neighbours of the one who likes Black. Only two people sit between A and the one who likes Black. A faces the one who likes Brown. D is an immediate neighbour of E. So only two places left for D and E. so I can be either at 2nd or 3rd to the left end of the 2nd row. Now we know that G is not an immediate neighbour of I and faces the one who likes Red. I does not like Brown. G does not sit at the extreme end of the line. It means G sits 2nd to the right end of the 2nd row. So I sits 2nd to the left end of the 2nd row. I faces immediate neighbours of E. so E sits right end of the 1st row. F faces the one who likes Violet. F does not like White. So F sits right end of the row and H sits at the centre of the row.  The one who likes Pink sits to the immediate right of the person who likes Orange. J 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.
