5) T and G sit immediate right to each other.

6) G and L do not sit immediate next to each other.

7) G and I do not sit immediate next to each other.

8) X faces towards the centre. So, I also face inward direction.

9) L and I face in opposite direction so, L faces away from centre.

10) G and L face in same direction so, G faces outward direction. Since, T and G sit immediate right to each other so T faces towards the centre.

11) M and V faces in opposite direction.

12) T and D do not face in same direction. Since in case 1(a)(i) after applying all condition the last condition will contradict so this case is eliminated. In case 1(a)(ii) and 1(b) condition 5 contradicts, in case 2(a) condition 4 and 12 contradicts so these cases are eliminated. Hence, the final arrangement is as follows

Since, I sits immediate right to M and the person who sits second left of I is D. 

Hence, the correct answer is D.

Eight persons :  L, M, N, O, P, Q, R and S

1. Four of them are facing away from the centre.

2. L who is facing away from the centre sits second to the left of S.

3. S is facing towards the centre.

4. S is sitting opposite N who is an immediate neighbour of R and Q.

5. P sits between M and Q and is facing away from centre. 

6. R and Q face the direction same as M.

Here as we know that four persons are facing towards the centre and others are facing away from centre.  The above condition fulfils if R, Q and M face towards the centre. 

This also implies that O sits to the immediate left of S. Also, O and N are facing away from centre.

The above arrangement will be the final arranegemnt.

Hence, P sits second to the right of N.

Eight people: A, B, C, D, E, F, G and H

People who are facing the inward direction = A, B

People who are facing the outward direction = C, D, E, F, G, and H

1) A is sitting second to the right of H. As it is a circular arrangement, we can randomly pick a seat for H and then we can place accordingly.

2) B sits third to the left of A. It implies, B is sitting third to the left of H. Also, now that we have identified the seats of A and B, we can safely mark other seats as outward-facing seats.

3) G is neither an immediate neighbour of B nor A. It implies, G is sitting to the immediate left of H as it is the only possibility.

4) D sits second to the right of G. It implies, D is sitting to the immediate right of H.

5) E and F are immediate neighbours and are facing outside.It implies, E and F are sitting between A and B as it is the only possibility. Also, now there is only one seat left for C i.e. the seat between B and G.

Clearly, C is sitting third to the left of D.

Person: P, Q, R, S, T, U, V, & W.

1). There are two-person sitting between V and S, and V is facing the center.

2). T sits second to the right of V.

3). R sits immediately left of T, who is facing the center.

4). W sits third to the left of R. 

5). Q and U are immediate neighbors of each other and U faces outsides.

6). Both the neighbors of V face different directions. (This means U cannot be a neighbor of V, as R faces outside).

7). Both the neighbors of T face outside.

8). P is not a neighbor of U. (Here Case 2 eliminates)

9). W and S are immediate right to each other. ( From here, case 2 gets eliminated).

The final arrangement is:

Hence, V is third to the right of P.

Persons - P, Q, R, S, T, U, V and W.

1) Q sits second to the left of R. Thus. Two cases can be formed as R’s direction is unknown.

2) Only 3 people sit between R and S.

3) T is not an immediate neighbour of Q and R.

4) T is an immediate neighbour of the one who is second to the left of S.

Thus, in Case I, S must face outside and T would be immediate left of S. And in Case II, S must face inside and T would be immediate left of S.

5) P and U are immediate neighbours of each other.

6) V faces inside.

7) W sits second to the left of V.

8) P sits opposite to W. Thus, Case I will get rejected. Also, Only three people were facing inwards so rest people will face outwards.

Eight people: A, B, C, D, E, F, G, and H sitting around a table.

Some of them are facing the centre while others are facing outside (i.e. opposite to the centre)

1)  F faces the centre.

2) Only three people sit between F and A.

3) C sits third to the left of A.

4) Immediate neighbors of C face the same direction

5) H is an immediate neighbor of F.

6) B is an immediate neighbor of H.

7) G sits to the immediate right of B.

8) D sits second to the left of G.

9) Immediate neighbors of D faces the opposite direction.

(As in the case ii, Immediate neighbors of D faces the same direction, case ii gets eliminated).

10) E sits to the immediate left of C.

11) Both D and H face a direction opposite to that of E.

Hence, G sits second to the left of H.

8 People: P, Q, R, S, T, U, V and W.

8 colors: Red, Yellow, Green, Orange, Blue, White, Pink, and Black

Facing directions: 4 people are facing inside and other 4 are facing outside.

1) The one who likes blue is not facing outside.

2) U is sitting fifth to the left of the one who likes blue.

3) Only one person is sitting between U and the one who likes orange.

4) P is sitting third to the right of the one who likes orange. 

5) Two persons are sitting between P and W.

6) W doesn’t like orange.

So, case 2 gets eliminated.

7) Neither W nor P is an immediate neighbour of Q.

8) The one who likes yellow is sitting third to the right of Q.

9) R and T are the immediate neighbours.

10) R is not an immediate neighbour of W nor he likes orange. 

11) The one who likes White is an immediate neighbour of S.

12) S is sitting third to the left of R.

This condition doesn’t satisfy in case 1(b) so this case gets eliminated.

13) The one who likes Red is sitting second to the left of the one who likes green.

14) R neither likes red nor black.

So, V likes Green and S likes Red.

Thus, we get that R likes Pink and W likes Black and the final arrangement will be as follows:

Hence, W black color.

Eight friends A, B, C, D, E, F, G and H are sitting around a circular table.

Note – Four of them are facing the centre, while four of them are not facing the centre and also not more than two persons facing the same direction can sit together.

1) F is an immediate neighbour of D.

2) Both the immediate neighbours of D are not facing the centre.

3) D sits on the immediate left of E.

 (Immediate neighbours of D are facing outside the centre and it is also given that D sits on the immediate left of E.)

(So, now direction of E and F can also be predicted, i.e, facing outside the center).

4) Both the immediate neighbours of E are facing the centre.

5) H sits second to the right of E.

6) B sits third to the right of H.

7) The one who is opposite to A is facing the centre.

8) C is an immediate neighbour of G, who sits second to the left of A.

9) Both the immediate neighbours of B are facing the same direction.

Above arrangement will be the final arrangement.

1. C is sitting fourth left of G and both of them facing opposite direction to each other.

2. I is sitting fourth right of C.

3. A sits fourth to right of F and F faces outside. Both F and A are not immediate neighbours to both C and I.

4. A and D are not neighbours, D sits second right of B, B is not a neighbour of C.

5.H sits immediate right of A, B sits third left of H.

6. G sits immediate right of I.

7. Only four people faces outside.(case 1 is eliminated because it has 5 persons already facing outside) so the case 2 is correct.

Hence, the person sitting second to the left of I is F.

Eight friends A, B, C, D, E, F, G and H are sitting around a circular table.

Note – Four of them are facing the centre, while four of them are not facing the centre and also not more than two persons facing the same direction can sit together.

1) F is an immediate neighbour of D.

2) Both the immediate neighbours of D are not facing the centre.

3) D sits on the immediate left of E.

 (Immediate neighbours of D are facing outside the centre and it is also given that D sits on the immediate left of E.)

(So, now direction of E and F can also be predicted, i.e, facing outside the center).

4) Both the immediate neighbours of E are facing the centre.

5) H sits second to the right of E.

6) B sits third to the right of H.

7) The one who is opposite to A is facing the centre.

8) C is an immediate neighbour of G, who sits second to the left of A.

9) Both the immediate neighbours of B are facing the same direction.

Hence, G sits on the immediate right of H.

Persons - P, Q, R, S, T, U, V and W.

1) Q sits second to the left of R. Thus. Two cases can be formed as R’s direction is unknown.

2) Only 3 people sit between R and S.

3) T is not an immediate neighbour of Q and R.

4) T is an immediate neighbour of the one who is second to the left of S.

Thus, in Case I, S must face outside and T would be immediate left of S. And in Case II, S must face inside and T would be immediate left of S.

5) P and U are immediate neighbours of each other.

6) V faces inside.

7) W sits second to the left of V.

8) P sits opposite to W. Thus, Case I will get rejected. Also, Only three people were facing inwards so rest people will face outwards.

Thus, Q sits immediate left of the person who sits second to the left of W.
