Read the following information to answer the question that follows:
(I) A, B, C, D, E, F and G are sitting in a circle facing the center and playing a game of cards.
(II) E is an immediate neighbour of A and D.
(III) C is not between F and G;
(IV) G is second to the right of F.
(V) F is to the immediate right of A.
Who are the immediate neighbours of B?
Read the following information to answer the question that follows:

(II) E is an immediate neighbour of A and D.
(III) C is not between F and G;
(IV) G is second to the right of F.
(V) F is to the immediate right of A.
Who are the immediate neighbours of B?
Solution
Given 7 people sitting in a circle facing the center: A, B, C, D, E, F, G
From condition (V): F is to the immediate right of A
Arrangement so far:
From condition (IV): G is second to the right of F
Going clockwise from F, there is one person between F and G.
Arrangement so far:
From condition (II): E is an immediate neighbour of both A and D
Since F is already to the right of A, E must be to the left of A.
Since E is also a neighbour of D, D must be adjacent to E on the other side.
Arrangement so far:
We now have 7 positions with B and C remaining to be placed.
The two empty positions are:
- Between F and G (position 5)
- Between G and D (position 7)
From condition (III): C is not between F and G
Therefore, C is NOT in position 5.
This means:
- Position 5 (between F and G): B
- Position 7 (between G and D): C
Final circular arrangement: (then back to D)
The immediate neighbours of B are F (to the left) and G (to the right).
Therefore, the answer is Option 3: F and G
