Given Information:

  • Seven people, P, Q, R, S, T, W and X sitting in a straight line facing north, not necessarily in the same order.

  • R sits at one of the extreme ends of the line.

  • T has as many people sitting on his right, as on his left.

  • S sits third to the left of X.

  • Q sits on the immediate left of W.

  • Q does not sit at any of the extreme ends of the line.



Question: If all the people are made to sit in alphabetical order from right to left, the positions of how many people will remain unchanged?

Solution:

  • From the given information, we can create the following diagram:

    R ? ? ? ? ? ?

  • Since R sits at one of the extreme ends of the line, we can assume that R sits at the extreme right end:

    R ? ? ? ? ? ?

  • From the given information, T has as many people sitting on his right, as on his left. Therefore, T must sit in the middle of the line:

    R ? ? T ? ? ?

  • From the given information, S sits third to the left of X. Therefore, X must sit at the extreme left end of the line and S must sit third to the left of X:

    R ? ? T ? ? S X

  • From the given information, Q sits on the immediate left of W. Therefore, Q must sit to the left of W:

    R ? ? T ? Q S X W

  • Now, we can arrange the people in alphabetical order from right to left:

    R ? ? T ? Q S X W
    W X ? ? T ? Q S R

  • The positions of only one person, i.e., Q, will remain unchanged. Therefore, the correct answer is option (B) One.



Therefore, the correct answer is option (B) One.
