We have, Z6 is sitting at one of the extreme ends. Persons sitting at extreme ends face opposite direction and no person is sitting left of Z6. Two persons are sitting between Z6 and Z2. Adjacent neighbors of Z2 are facing south direction. Case-1 Again we have, The one who is second to the right of Z4 is facing north and having 20 pens, but it is not Z6. Z3 and Z1 are facing in opposite direction and Z1 is not adjacent to Z6 and Z5. Z1 does not sit adjacent to Z3.
