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)
- Charan sits second to the right of the student from CHEMICAL. Reshma is an immediate neighbour
of the student who faces the student from CHEMICAL.
- Only one student sits between Reshma and the students from IT. Immediate neighbour of the student
from IT faces the student from EEE.
- The student from ECE faces the student from MECH. Reshma is not from MECH. Pavitra is not from
IT. Pavitra does not face the student from CHEMICAL.
- Qunie faces the student from EIE. The one who faces Shivani sits immediately to the left of Anil.
- Balu does not sit on any of the extreme ends of the line. The student from CHEMICAL does not face
the student from CSE.
Pavitra is related to EIE in the same way as Balu is related to IT based on the given arrangement. To
who amongst the following is David related to, following the same pattern?
