Arrangement Logic for Six Students
We need to determine the seating arrangement of six students (A, B, C, D, E, F) around a circular table based on the given clues.
- Clue 1: D sits second to the right of E.
- Clue 2: F sits second to the right of D.
- Clue 3: F is an immediate neighbour of A.
- Clue 4: A is not an immediate neighbour of E.
- Clue 5: B is an immediate neighbour of E.
- Clue 6: B sits second to the right of C.
Step-by-Step Seating Determination
Let's place the students step-by-step, assuming clockwise direction for "right":
- From Clue 1 (D second to right of E) and Clue 2 (F second to right of D), we can establish a partial sequence: E, _, D, _, F, _.
- From Clue 3 (F is neighbor of A), A must be in the position immediately to the left or right of F.
- From Clue 4 (A is not neighbor of E), A cannot be in the position immediately to the left of E. Combining this with the sequence from Step 1, A must be between D and F. The sequence becomes: E, _, D, A, F, _.
- The remaining students are B and C, and the remaining seats are between E and D, and between F and E.
- From Clue 5 (B is neighbor of E), B must be in one of the seats adjacent to E.
- From Clue 6 (B sits second to the right of C). Let's test the two possibilities for B:
- If B is placed between E and D, the arrangement is E, B, D, A, F, _. C must be in the last seat. The arrangement is E, B, D, A, F, C. Let's check Clue 6: Is B (pos 2) second to the right of C (pos 6)? Yes. This arrangement fits all clues.
- If B is placed between F and E, the arrangement is E, _, D, A, F, B. C must be between E and D. The arrangement is E, C, D, A, F, B. Let's check Clue 6: Is B (pos 6) second to the right of C (pos 2)? Yes. However, this contradicts Clue 5 (B is neighbor of E). In E, C, D, A, F, B, B is not a neighbor of E. So this possibility is invalid.
- The confirmed clockwise arrangement is: E, B, D, A, F, C.
Finding Students Between E and A
The question asks: "Who sit between E and A from the right of A?"
- Find A in the arrangement: E, B, D, A, F, C.
- Consider the direction "from the right of A" (clockwise).
- The sequence moving clockwise from A is: A, F, C, E, B, D.
- We need to identify the students sitting between E and A in this clockwise direction.
- Following the sequence A, F, C, E..., the students between A and E are F and C.
Therefore, F and C sit between E and A from the right of 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
