**Answer the following questions based on the information given below.**

Who is fourth from the south?

- A.
R

- B.
T

- C.
S

- D.
U

Answer: Option D

**Explanation** :

If people face the west, they can be numbered 1-7 (from north to south), as shown:

7

6

5

4

3

2

1

This is equivalent to a floor arrangement of seven people on seven floors.

S is third from the north. and R is to the immediate right of S i.e. S = 5 and R = 6.

7

R

S

4

3

2

1

Q is at an extreme and T is his neighbour. Since QT have to be together, Q = 1 and T = 2

V is between T and U. Since T = 2, V = 3, U = 4.

Hence, P takes the only remaining places i.e. 7. Thus, the final arrangement is:

(North)

P

R

S

(West) U (East)

V

T

Q

(South)

Thus, U is fourth from south.

Hence, option (d).
