Daily Olympiad: Logical Reasoning - Seating Arrangement [20260511]

Solution

Correct: B

Fix A and B's positions first. C and D occupy adjacent seats on the right of A. F and E cannot be adjacent. The only non-adjacent pairs are F-G-E or E-G-F. G's opposite is determined by fixing remaining positions based on constraints. After mapping, the person opposite G is B.

Solution

Correct: B

Fix S and R's positions first. Q cannot be in first or last, so must be in 2nd, 3rd, or 4th. R must be to the right of S but not adjacent, narrowing positions to S in 1st and R in 3rd or 4th. Combining all constraints, Q is third from the left.

Solution

Correct: D

Row 2: Place W and X such that W is third to the right of X. Row 1: B and C are adjacent. Only positions possible for B and C allow D (in row 2) to face B. Deduce via elimination and adjacency constraints.

Solution

Correct: C

Place M between L and N first. P opposite Q creates a symmetry. O's position excludes adjacency to L. The only valid configuration places N and O adjacent to Q due to elimination of conflicting options.

Solution

Correct: D

Square tables with sides corresponding to directions. K and L's positions fix two seats. Since M faces north, the remaining N must face east. All directional constraints align with this arrangement.
