A, B, C, D, E and F are sitting around a circular table facing the centre (not necessarily in the same order). B is sitting to the immediate right of F and immediate left of C. C is sitting to the immediate left of E. A is sitting to the immediate right of E and to the immediate left of D. Who is sitting to the immediate left of F?
A
C
D
B
D
Fix one person (F) and place the others based on immediate relational constraints in a single rotational sequence.
Fix one person (F) and place the others based on immediate relational constraints in a single rotational sequence.
Establish the initial chain
B is to the immediate right of F. Since B is also to the immediate left of C, the sequence is F тЖТ B тЖТ C.
Incorporate the next constraint
C is to the immediate left of E, so E sits to the right of C. Current sequence: F тЖТ B тЖТ C тЖТ E.
Complete the circle
A is to the immediate right of E, and A is to the immediate left of D. Current sequence: F тЖТ B тЖТ C тЖТ E тЖТ A тЖТ D. Following the circle, D is to the immediate left of F.
A: A is to the immediate right of E, not left of F. B: B is to the immediate right of F, not left. C: C is to the immediate right of B, not left of F.
C is correct because according to the derived circular order F-B-C-E-A-D, D occupies the position immediately to the left of F.
In circular puzzles, always draw the chain linearly first and close the circle at the final step to ensure all neighbors are correctly accounted for.
