Solving the Circular Table Seating Arrangement
This problem involves arranging eight girls (A, B, C, D, E, F, G, H) around a circular table, all facing the center. The goal is to find who sits to the immediate right of F.
Decoding the Seating Clues
We will determine the seating arrangement step-by-step using the provided clues:
- Clue 1 & 2: 'A is second to the left of D' and 'D is third to the left of E'. Assuming positions are counted clockwise, this establishes a relative order. Let E be at position 1. Then D is 3 positions to the left, placing D at position 6 (1 -> 8 -> 7 -> 6). A is 2 positions to the left of D, placing A at position 4 (6 -> 5 -> 4).
Current partial arrangement (clockwise): E _ _ A _ D _ _ (Positions 1, 4, 6 are occupied).
- Clue 6 & 5: 'B is second to the right of G' and 'H is third to the right of B'. This implies the sequence G ... B ... H.
- Clue 3: 'C is third to the right of G'. This implies the sequence G ... C.
- Clue 4: 'G is not the immediate neighbour of E'. Since E is at position 1, G cannot be at positions 2 or 8.
Determining the Final Arrangement
The remaining positions are 2, 3, 5, 7, 8. The people to place are B, C, F, G, H. G cannot be at 2 or 8, leaving positions 3, 5, or 7 for G.
- Test G at position 3: E _ G A _ D _ _. B (2nd right of G) is at 5. H (3rd right of B) is at 8. C (3rd right of G) should be at 6, but D is already there. This is not possible.
- Test G at position 7: E _ _ A _ D G _. B (2nd right of G) would be at position 1 (7+2=9 mod 8), but E is already there. This is not possible.
- Test G at position 5: E _ _ A G D _ _.
- B (2nd right of G) is at position 7 (5+2=7). Arrangement: E _ _ A G D B _.
- H (3rd right of B) is at position 2 (7+3=10 mod 8). Arrangement: E H _ A G D B _.
- C (3rd right of G) is at position 8 (5+3=8). Arrangement: E H _ A G D B C.
Check Clue 4: G (at 5) is not adjacent to E (at 1). E's neighbours are H (at 2) and C (at 8). This arrangement is valid.
Identifying the Person to the Right of F
The final confirmed clockwise seating arrangement is:
| Position: | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 |
| Person: | E | H | F | A | G | D | B | C |
F is sitting at position 3.
The person sitting on the immediate right of F is at position 4, which is A.
Important Questions from Circular Arrangement
Eight students A, B, C, D, E, F, G and Hsit around a circular table, equidistant from each other, facing the centre of the table, not necessarily in the same order. Band Dsit neither adjacent to Cnor opposite to C. Asits in between Eand D, and Fsits in between Band H. Which one of the following is definitely correct?
Six persons A, B, C, D, E and Fare sitting equidistant from each other around a circular table (facing the centre of the table).
Consider the Question and two Statements given below :
Question : Who is sitting on the immediate left of A?
Statement-1 : Bis sitting opposite to Cand Dis sitting opposite to E.
Statement-2 : Fis sitting on the immediate left of B.
Which one of the following is correct in respect of the Question and the Statements?
Seven persons P, Q, R, S, T, U and V are sitting around a circular table facing the center (not necessarily in the same order). T sits third to the right of R. V sits third to the right of Q. One person sits between P and T. P is not the neighbor of S. U sits third to the left of P. Who sits second to the left of S?
Akash, Binita, Chandan, Daksh, Ekta & Fatima are standing in a circle. Binita is between Daksh & Chandan. Akash is between Ekta & Chandan. Fatima is to the right of Daksh. Who is between Akash & Fatima?
Six friends A, B, C, D, E and F are sitting around a round table in such a way that A is between E and F, E is opposite to D, and C is not on either side of E. The person opposite to D is
