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?
Explanation
Given the arrangement based on the clues, the seating order is P, Q, R, S, T, U, V, W. When Q moves clockwise, they will cross R, S, T, U, and V before reaching W, which totals five persons crossed.
