They also like different sports like Archery, Polo, Rugby, Taekwondo, Wrestling, Squash, Gymnastics, and Baseball but not necessary in the same order.
 
Either Deependu or Balbir sits at the extreme end of the row. Anant likes Baseball and sits second from the left end of the row. Deependu sits third to left of one who likes Gymnastics. Balbir sits third to left of Gandhik, who likes Squash. Gandhik does not sit the extreme end of the line. The one who likes Wrestling sits second to left of Faiyaz.

Final arrangement:
 

 
Common explanation:
 
Reference:
 
Anant likes Baseball and sits second from the left end of the row.
 
Inference:
 


Reference:
 
Deependu sits third to left of one who likes Gymnastics. Balbir sits third to left of Gandhik, who likes Squash.
Either Deependu or Balbir sits at the extreme end of the row.

 
Inference:
As all of them are facing north and Deependu and Balbir sits at the left of someone therefore they are not sitting at the extreme right end of the row but either one of them is sitting at extreme left end.
 
Reference:
 
No two successive students are sitting together according to alphabetical order.
 
Inference:
Therefore, Balbir cannot sit at the extreme left end as Anant is sitting at second position and they cannot be the neighbor, so Deependu is sitting at the extreme left end of the row and is third to the left of one who likes Gymnastics.
 

 
Reference:
 
Balbir sits third to left of Gandhik, who likes Squash. Gandhik does not sit the extreme end of the line.
One of the immediate neighbors of Balbir likes Taekwondo.


Inference:
So, Gandhik can sit at second position from right and Balbir should be the one who likes Gymnastics.
 

 
Reference:
 
The one who likes Wrestling sits second to left of Faiyaz.
Faiyaz does not like Taekwondo.
The one who likes Rugby sits second to right of one who likes Archery.


Inference:
 

 
As per the first reference, the one who likes Wrestling and the Fayaz can sit at three places:
A  AA B- or C C-

But as, Faiyaz does not like Taekwondo and Balbir have a neighbor who likes Taekwondo so A- B- position cancels.
 
Now two cases arise:
 
Case 1



Case 2


 
But, as no two successive students are sitting together according to alphabetical order, therefore, case 2 fails here.
 
Reference:

Ekansh does not sit any of the extreme end of the line.

Inference:
Now, Chakshu, Hriday and Ekansh left to be placed and we also have to follow the rule of not having two successive students sitting together according to alphabetical order.
