Question
Who among the following person sits second to the right
of the one who faces the one who likes White? Study the following information carefully and answer the questions given below. Eight persons are sitting in two parallel rows facing towards each other. In row 1 – A, B, C, and D are sitting and facing towards north while in row 2 – P, Q, R, and S are sitting and facing towards south, but not necessarily in the same order. They like different colours – Red, Yellow, Green, Blue, Black, Orange, White and White. Only one person sits between A and the one who faces the one who likes white, who doesn’t sit at the ends of the row. D sits immediate right of the one who faces the one who likes white. Only one person sits between Q and the one who faces D. P is the only neighbour of the one who faces the one who likes yellow, who doesn’t face Q. C sits second to the left of the one who faces the one who likes red, which is not liked by R. The one who likes green sits to the left of C, who doesn’t like orange. D neither likes blue nor white. As many persons sit to the right of B as to the left of the one who likes orange.Solution
We have, Only one person sits between A and the one who faces the one who likes white, who doesn’t sit at the ends of the row. D sits immediate right of the one who faces the one who likes white From this condition, there are two possibilities
Again we have, Only one person sits between Q and the one who faces D. P is the only neighbour of the one who faces the one who likes yellow, who doesn’t face Q.
Again we have, C sits second to the left of the one who faces the one who likes red, which is not liked by R. The one who likes green sits to the left of C, who doesn’t like orange. D neither likes blue nor white. As many persons sit to the right of B as to the left of the one who likes orange from the above condition, case 1 gets eliminated. Hence, case 2 shows the final arrangement.
