Directions: Read the following information carefully and answer the questions given below.

Eight individuals—P, Q, R, S, T, U, V, and W—are seated around a rectangular table. Four of them sit at the corners facing towards the centre, while the other four sit at the middle of the four sides facing away from the centre.
W sits at one of the middle of the sides and sits third to the right of S. R sits to the immediate right of U, who sits at one of the corners. Only two persons sit between R and Q. P sits second to the left of R. V sits to the immediate left of P. T sits to the immediate right of Q. W sits to the immediate right of V.

Four of the following five are alike in a certain way based on their seating positions and thus form a group. Which among the following does not belong to that group?

The correct answer is R.

Step-by-step Explanation:

We are given that eight individuals—P, Q, R, S, T, U, V, and W—are seated around a rectangular table:
• Four persons sit at the corners facing towards the centre.
• Four persons sit at the middle of the four sides facing away from the centre.

Let us deduce the arrangement step-by-step:
1. Positions of W and S: W sits at the middle of one of the sides and sits third to the right of S. Since W is at a middle position (facing away), S must sit at one of the corners (facing towards the centre).
2. Positions of U and R: U sits at a corner (facing towards the centre). R sits to the immediate right of U, which places R at an adjacent middle position (facing away from the centre).
3. Position of Q: Only two persons sit between R and Q. Placing Q two seats away from R positions Q at a corner (facing towards the centre).
4. Positions of P and V: P sits second to the left of R. Since R faces away from the centre, counting second to the left places P at a middle side. V sits to the immediate left of P, placing V at a corner (facing towards the centre).
5. Positions of T and W: T sits to the immediate right of Q (at a middle side). W sits to the immediate right of V, completing the seating arrangement in full harmony with all clues.

Summary of Seating Positions:
• Corner positions (Facing Towards Centre): S, U, Q, V
• Middle of sides (Facing Away from Centre): W, R, P, T

Evaluating the Options:
• U, S, Q, and V all sit at the corners facing towards the centre.
• R sits at the middle of a side facing away from the centre.
Hence, R does not belong to the group.
