Nine persons - A, B, C, D, E, F, G, H and I are sitting on a circular table. Five persons are facing outside while four are facing inside. Not more than two persons facing the same direction are sitting together. F is sitting third to the right of A who is facing inside. Three persons are sitting between F and E. B and G are sitting immediate left of each other. C is sitting third to the right of H who is one of the neighbours of A. H is not facing outside. Two persons are sitting between D and I who is adjacent to C. E, who is not sitting adjacent to B, is one of the immediate neighbours of H. F is sitting to the immediate left of C while to the immediate right of D.

F
BOption (b)
H
COption (c)

DOption (d)
A
EOption (e)
D

View answer & explanation

Correct answer

E.

D

Why this answer is correct

Persons: A, B, C, D, E, F, G, H and I

Five persons are facing outside while four are facing inside.

1) F is sitting third to the right of A who is facing inside.

Three persons are sitting between F and E.

Since it is not clear E is sitting in which direction with respect to F, two cases will be formed.

Case 1:

Case 2:

3) C is sitting third to the right of H who is one of the neighbours of A.

H is not facing outside.

In case 2, H can either sit to the right of A or to the left of A. So, two cases can be formed.

Case 1:

Case 2(a):

Case 2(b):

5) Two persons are sitting between D and I who is adjacent to C.

6) E, who is not sitting adjacent to B, is one of the immediate neighbours of H.

E is the neighbour of H only in case 2(b). So other cases will be cancelled.

7) B and G are sitting immediate left of each other.

From point 6, E cannot sit adjacent to B, so the diagram will be as follows:

8) F is sitting to the immediate left of C while to the immediate right of D.

9) Not more than two persons facing the same direction are sitting together.

All except D are facing inside while D is facing outside.

Hence, D does not belong to that group.
