**Answers & Solutions:**

**1)Â AnswerÂ (E)**

Let the numbering of the rows be as shown below:-

The number of people to the right and to the left of F is the same.

Thus, F sits either at 3 or at 8.

Let us fix the position of F at 3.

C sits to the immediate right of the person sitting opposite F.

Thus, C sits at 9.

A and C sit in the same row but are not neighbours.

Thus, A can either sit at 6 or at 7.

One of the neighbour of A has only A as his neighbour.

Thus, A must sit at 7.

A and H sit opposite each other.

Thus, H sits at 2.

E and F are sitting in the same row but E is not sitting at any corners.

Thus, E must sit 4.

B has 2 neighbours.

Thus, B must sit at 8.

J has H to his left and is facing I.

Thus, J and I are sitting at 1 and 6.

Thus, D and G are sitting at 5 and 10 in any order.

The seating arrangement is as shown below:-

Thus, as we do not know the position of D we cannot determine who else is facing North.

Hence, option E is the correct answer.

**2)Â AnswerÂ (B)**

V and W are the neighbors of T. Hence; they must be at 2 and 4 in any order.

Q is sitting exactly in between S and U. Hence, Q must be seated at 7.

R is a neighbour of U. Hence, U must be seated at 6 and S must be seated at 8.

Q and T are facing North whereas their neighbors are facing South.

Hence, V, W, U and S are facing south.

The seating arrangement of the friends is as shown below:-

Hence, 2 people are facing North.

Hence, option E is the correct answer

**17)Â AnswerÂ (A)**

The solution is on the basis of the following arrangement:-

Given that, P is sitting at one of the corners facing South.

P can sit at 1 or 8.

P sits 4th to the right of R and R sits 4th to the left of P. Hence, R must be seated at 5 facing South and P must sit at 1.

T is equidistant from P and R. Hence, T must be seated at 3.

V and W are the neighbors of T. Hence; they must be at 2 and 4 in any order.

Q is sitting exactly in between S and U. Hence, Q must be seated at 7.

R is a neighbour of U. Hence, U must be seated at 6 and S must be seated at 8.

Q and T are facing North whereas their neighbors are facing South.

Hence, V, W, U and S are facing south.

The seating arrangement of the friends is as shown below:-

Hence, only 1 person sit in between U and S.

Hence, option A is the correct answer.

**18)Â AnswerÂ (D)**

The solution is on the basis of the following arrangement:-

P can sit at 1 or 8.

P sits 4th to the right of R and R sits 4th to the left of P. Hence, R must be seated at 5 facing South and P must sit at 1.

T is equidistant from P and R. Hence, T must be seated at 3.

V and W are the neighbors of T. Hence; they must be at 2 and 4 in any order.

Q is sitting exactly in between S and U. Hence, Q must be seated at 7.

R is a neighbour of U. Hence, U must be seated at 6 and S must be seated at 8.

Q and T are facing North whereas their neighbors are facing South.

Hence, V, W, U and S are facing south.

The seating arrangement of the friends is as shown below:-

Hence, Q is sitting 4th to the right of T.

Hence, option D is the correct answer.

**19)Â AnswerÂ (C)**

The solution is on the basis of the following arrangement:-

P can sit at 1 or 8.

P sits 4th to the right of R and R sits 4th to the left of P. Hence, R must be seated at 5 facing South and P must sit at 1.

T is equidistant from P and R. Hence, T must be seated at 3.

V and W are the neighbors of T. Hence; they must be at 2 and 4 in any order.

Q is sitting exactly in between S and U. Hence, Q must be seated at 7.

R is a neighbour of U. Hence, U must be seated at 6 and S must be seated at 8.

Q and T are facing North whereas their neighbors are facing South.

Hence, V, W, U and S are facing south.

The seating arrangement of the friends is as shown below:-

Hence, S is sitting at one of the ends.

Hence, option C is the correct answer.

**20)Â AnswerÂ (C)**

The solution is on the basis of the following diagram:-

From 3, it is clear A is sitting at 1.

From 8, it is clear that Q is sitting at 8.

From 1, it is clear that P is sitting at either 7 or 9.

But if P sits at 1 then it cannot face D. Hence, P sits at 9 and D sits at 3.

From 7, it is clear that T sits at 10.

From 4, it is clear that E is sitting at 5.

From 6, it is clear that F is sitting at 2.

From 2, it is clear that C sits at 6 and R sits at 6.

From 5, it is clear that A is facing S and E is facing U.

Hence, the seating arrangement of the 12 friends is as shown below:-

Hence, if T and U exchange their position then E is now sitting opposite T.

Hence, option C is the correct answer.
