Question 1
Six persons B, E, A, F, D and C are sitting around a circular table facing the center.
B sits second to the left of E. A sits opposite to B.
F sits immediately to the right of A. C is not adjacent to F.
Who sits opposite to E?
Solution Approach:
Step 1: Draw circular diagram
6 persons facing center. Opposite positions are 3 seats apart.
Number positions 1–6 clockwise.
Step 2: Place definite positions
- Fix B at position 1 (reference point)
- B is second to the LEFT of E → E is 2 clockwise from B
pos[E] = 3
- A sits OPPOSITE B (pos 1) → pos 4
- F sits immediately to the right of A (pos 4) → pos 5
Step 3: Resolve remaining positions
Remaining persons: C, D → remaining seats: [2, 6]
C is NOT adjacent to F (pos 5).
Adjacent to pos 5: pos 4 and pos 6.
Therefore C → pos 2, and D → pos 6.
Final Arrangement (clockwise):
pos1:B → pos2:C → pos3:E → pos4:A → pos5:F → pos6:D
(All facing center)
Opposite pairs: pos1↔pos4, pos2↔pos5, pos3↔pos6
E is at pos 3 → opposite = pos 6 = D
Answer: D sits opposite to E.

E is at pos 3 → opposite = pos 6 = D
Answer: D sits opposite to E.
