Question 1

Six persons A, B, E, F, C and D are sitting around a circular table facing the center. A sits second to the left of B. E sits opposite to A. F sits immediately to the right of E. D is not adjacent to F. Who sits opposite to B?
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 A at position 1 (reference point)
- A is second to the LEFT of B → B is 2 clockwise from A
pos[B] = 3
- E sits OPPOSITE A (pos 1) → pos 4
- F sits immediately to the right of E (pos 4) → pos 5

Step 3: Resolve remaining positions
Remaining persons: D, C → remaining seats: [2, 6]
D is NOT adjacent to F (pos 5).
Adjacent to pos 5: pos 4 and pos 6.
Therefore D → pos 2, and C → pos 6.

Final Arrangement (clockwise):
pos1:A → pos2:D → pos3:B → pos4:E → pos5:F → pos6:C
(All facing center)

Opposite pairs: pos1↔pos4, pos2↔pos5, pos3↔pos6

B is at pos 3 → opposite = pos 6 = C

Answer: C sits opposite to B.
