Eight students from different Departments viz. ECE, CSE, EEE, IT, EIE,
MECH, CIVIL and CHEMICAL are sitting in two parallel rows containing
four students each, in such a way that there is equal distance between
adjacent persons. In row 1 - Anil, Balu, Charan, David is seated and all
of them are facing south. In row 2 - Pavitra, Qunie, Reshma, Shivani are
seated and all of them are facing north. Therefore each member
seated in a row faces another member of the other row. (All the
information given above does not necessarily represent the order of
seating in the final arrangement)
R
- Charan sits second to the right of the student from CHEMICAL
