Answer & explanation
Correct answer: option 4
X is at one end of the row. W is seated adjacent to both X and V.
CASE 1:
X W V _ _ _ _ _ _
CASE 2:
_ _ _ _ _ _ V W X
U is to the immediate right of V and at the third place to the left of E.
CASE 1:
X W V U _ _ E _ _
CASE 2:
It is not possible as W is immediate right of V. So, case 1 is the only possibility.
S is immediate left of E. E is at the second place to the left of R.
X W V U _ S E _ R
N is immediate right of E. So, the only position for M is to immediate left of S.
X W V U M S E N R
So, X and R are sitting at the extreme ends.
