(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.

Which of the conditions (i) to (v) given above is not required to find out the place in which A is sitting ?

A. (i)
B. (ii)
C. (iii)
D. All are required
E. None of these
Answer: D . All are required


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 →

All the statements are required to determine the correct sequence.
