Question

Eight persons P, Q, R, S, T, U, V and W sit around a round table in eight different seats placed with equal distance between any two consecutive seats. Both P and R are adjacent to Q. Both T and R are adjacent to S. Both U and W are adjacent to V. S and W are on opposite chairs. If while going in the clockwise direction around the table from P, one meets R before T, then how many persons shall Q cross while moving in the clockwise direction around the table before meeting W?

1. A. 5 (Correct answer)
2. B. 4
3. C. 2
4. D. 1

Correct Answer

Option A — 5

Detailed Solution & Explanation

The correct answer is Option A (5 persons).

Key Points

• Q sits between P and R; S sits between R and T, giving the block P–Q–R–S–T. V sits between U and W, giving U–V–W.
• With S and W opposite on 8 seats and R met before T clockwise, the clockwise order fixes as P, Q, R, S, T, U, V, W (W lands exactly opposite S).

Additional Information

• Moving clockwise from Q, one passes R, S, T, U, V — 5 persons — before reaching W. Hence Option A.
