(i). A, B, C, D, E, F and G are sitting on a wall and all of them are facing east.
(ii). C is on the immediate right of D.
(iii). B is at an extreme end and has E as his neighbour.
(iv). G is between E and F.
(v). D is sitting third from the south end.

Name the person who should change places with C such that he gets the third place from the north end.

A. E
B. F
C. G
D. D
Answer: C . G


C is to the right of D.
D is third from south. So, B will be at the extreme end from north because it should have E as its neighbour. G is between E and F.
So the Sequence is :
B →
E →
G →
F →  East
D →
C →
A →

G should change place with C to make it third from north.
