Who is at the extreme left end ?
The boys are standing facing south. So, consider 'left' and 'right' accordingly.
Jayesh is to the right of Alok i.e. J, A.
Pramod is between Bhagat and Subodh i.e. B, P, S.
Subodh is between Jayesh and Pramod.
So, the sequence is :
Bhagat, Pramod, Subodh, Jayesh, Alok → South.
Alok is at the extreme left end.
