Explanation:

Q is placed fifth to the right of V. Also, Q is placed to the immediate left of R.
Therefore, the arrangement becomes
V __ __ __ __ Q R
Q and J are not placed immediately next to either Q or V.
Therefore, the arrangement becomes
V __ W J __ Q R
or V __ J W __ Q R
However the word formed cannot be determined using this statement.
Thus, the question cannot be answered using Statement I alone.
From statement II:
M is placed to the immediate left of W, but is not an immediate neighbour of Q. N is placed second to the left of R.
__ M W __ N __ R
However, the word formed cannot be determined using this statement.
Thus, the question cannot be answered using Statement II alone.
From statements I and II together:
N is placed to the immediate left of W.
Therefore, the arrangement becomes
V M W J __ Q R
Thus, the question can be answered using both statements I and II together.
