Question: Who sits exactly between B and A?
Explanation:
Number the seats 1-8 as shown:
A faces the centre and H is third to the right of A. Let A be seated on seat 1. Hence, H sits on seat 6.
Also, the person opposite H faces outside. Hence, the person on seat 2 faces outside.
C is not an immediate neighbour of A or H. Hence, C sit on seat 3 or 4. Also, C faces outside.
B is third to the right of C. If C is on seat 3, H is already third to his right. Hence, C cannot be on seat 3. Hence, C is on seat 4 and B sits on seat 7.
G is second to the left of B. If B faces the centre, A is already second to the left of B. Hence, B faces outside and G is on seat 5.
Hence, all three people facing outside are found (B, C, seat 2). Hence, the remaining people (A, H. seats 3, 5, 8) face the centre.
C is second to the right of F. Hence, F faces outside and is on seat 2.
D is third to the left of E. Since both face the centre, E is on seat 8 and D is on seat 3. Hence, the final arrangement is:
Hence, E sits exactly between B and G.
Hence, option (c).
