(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.
Answer: C
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.

Rohit, Kunal, Ashish and John are students of a school. Three of them stay far from the school and one near it. Two study in class IV, one in class V and one in class VI. They study Hindi, Mathematics, Social Science and Science. One is good at all the four subjects while another is weak in all of these. Rohit stays far from the school and is good at Mathematics only while Kunal is weak in Mathematics only and stays close to the school. Neither of these two nor Ashish studies in class VI. One who is good at all the subjects studies in class V.
