Q

Circular Table Arrangement

Seven individuals (L, M, N, O, Q, R, S) are seated around a circular table facing the center. The task is to determine the seating order based on the clues and find who sits third to the left of S.

Logic Clues Analysis

  • Clue 1: "Only two people sit between O and R when counted from the right of O." This means there are 3 positions clockwise from O to R (O, P1, P2, R).
  • Clue 2: "Only two people sit between R and M." This implies a 3-position gap clockwise from R to M (R, P3, P4, M).
  • Clue 3: "Only three people sit between O and N." In a 7-person circle, O and N are diametrically opposite.
  • Clue 4: "L sits to the immediate left of Q." Facing the center, this forms an adjacent 'LQ' block.

Deductive Arrangement Steps

Assign positions 1 through 7 clockwise.

  1. Assume O is at position 1.
  2. From Clue 1 (O _ _ R clockwise), R is at position $1 + 3 = 4$.
  3. From Clue 3 (O opposite N), N is at position $1 + 4 = 5$.
  4. From Clue 2 (R _ _ M clockwise), M is at position $4 + 3 = 7$.
  5. The current clockwise structure is: O(1), _(2), _(3), R(4), N(5), _(6), M(7).
  6. Remaining people: L, Q, S. Remaining seats: 2, 3, 6.
  7. Clue 4 establishes the 'LQ' block. The only adjacent empty seats are 2 and 3. Thus, L occupies seat 2, and Q occupies seat 3.
  8. The remaining person, S, takes seat 6.

Final Arrangement Confirmed

The clockwise seating order is: O, L, Q, R, N, S, M.

Position Third Left of S

The question asks for the person third to the left of S. Since the table faces the center, "left" refers to the counter-clockwise direction.

S is at position 6.

  • 1st person counter-clockwise from S (pos 6) is N (pos 5).
  • 2nd person counter-clockwise from S (pos 6) is R (pos 4).
  • 3rd person counter-clockwise from S (pos 6) is Q (pos 3).

Therefore, Q sits third to the left of S.
