Difficulty: Medium
Correct Answer: B and F
Explanation:
Introduction / Context:Seating-arrangement questions test the ability to translate relational clues (left/right/opposite/between) into a consistent circular map. Here, six people sit around a table facing the centre. We must determine who sits immediately beside A using the given positional constraints about F, E, C and A.
Given Data / Assumptions:
Concept / Approach:In a circle facing the centre, “right of X” is the next clockwise seat from X. “Opposite” is three seats away (since 6 seats). “Between A and D” means F has A on one side and D on the other, so F’s immediate neighbours are A and D.
Step-by-Step Solution:
1) Place A arbitrarily (circular symmetry allows this) and enforce “C opposite A”, so C is three seats from A.2) Since F is between A and D, put F next to A; D must then be on F’s other side.3) Place E opposite F (given). With E fixed, place C immediately to the right of E (clockwise from E).4) The remaining seat belongs to B.5) Reading off A’s neighbours in the final consistent layouts gives B on one side and F on the other.Verification / Alternative check:Try the symmetric rotation (start A at a different seat). All valid rotations still force A’s neighbours to be B and F. Hence the answer is invariant under rotation.
Why Other Options Are Wrong:
F and D: F is a neighbour, but D is not adjacent to A in the consistent placements.E and F / E and C: E and C end up across or away from A due to opposite/right constraints.B and D: D is separated from A by F.Common Pitfalls:A frequent mistake is reversing “right of” when facing the centre, or misreading “between” as “somewhere in the arc”. Here, “between” means immediate adjacency on both sides of F.
Final Answer:B and F
