Hence, Michel sits third left of Abraham.

Hence, John & Michel are the immediate neighbors of Jack.

Hence, Micky is just left to Dany.

Hence, Hillary is second right to Dany.

Hence, Dany is sitting between Immy and Micky.

Persons: M, N, O, P, Q, R, S, T

5 – Facing Out

3 – Facing In

1. There are two persons gap between O and T and both are facing opposite direction.

2. P sits 3rd to the right of O.

3. Q sits opposite to T and facing the same direction as T.

In case (1), P sits third to right of O, if O facing inside then we can’t make P to third right of O. Same In case (2), if O facing outside then we can’t make P to third right of O.

4. M is neither the neighbor of T nor P.

5. There are three persons gap between M and P and both are facing opposite direction to each other.

6. M is facing opposite direction as Q is facing.

7. There are three persons gap between N and S and both are facing away from the centre.

8. R is sitting 2nd to the right of N and both the neighbors of R facing opposite to the R.

9. R is facing towards the centre.

Here Case (1) gets cancelled because It is clearly given that 3 persons are facing the centre and 5 facing outside the centre, but In case (1) if R is facing the centre than 4 persons are facing the centre that is not possible.

So our Final diagram is given below:

Hence, P is sitting 3^rd to the right of N.

Persons: M, N, O, P, Q, R, S, T

9. R is facing towards the centre.

Here Case (1) gets cancelled because It is clearly given that 3 persons are facing the centre and 5 facing outside the centre, but In case (1) if R is facing the centre than 4 persons are facing the centre that is not possible.

So our Final diagram is given below:

Hence, Q is sitting 4^th to left of T and also 4^th to the right of T.

Hence, O is sitting opposite to R.

Persons: A, B, D, H, I, N, S, and V

1) D is third to the right of A and none of them is sitting at the corner of a table.

2) One person is sitting between D and S.

There can be two cases:

Case 1:

Case 2:

3) Common neighbour of D and S is third to the left of B.

Case 1:

Case 2:

4) B is not an immediate neighbour of A.

This is not possible in case II, so case II is eliminated.

5) V is not an immediate neighbour of B or S.

6) V and I are sitting adjacent to each other

i.e. V is an immediate neighbour of I.

7) H is not sitting atany corner of the table.

So, H is sitting between D and S.

Now, only N is remaining, who will sit immediate left to B.

The final seating arrangement:

Hence, 2 persons are sitting between B and A.

Persons: A, B, D, H, I, N, S, and V

1) D is third to the right of A and none of them is sitting at the corner of a table.

2) One person is sitting between D and S.

7) H is not sitting atany corner of the table.

So, H is sitting between D and S.

Now, only N is remaining, who will sit immediate left to B.
