Seven persons- P, Q, R, S, T, U and V - are standing in a straight line facing north. What is the position of V from the right end of the line ?
I. Q stands at one of the extreme ends of the line. Only two persons are standing between Q and R. V is an immediate neighbour of R.
II. S stands at one of the extreme ends of the line. Only four persons are standing between S and T. V is an immediate neighbour of T.

Clearly, in each statement alone, there is not sufficient data to find the position of V, thus by combining both statements, we get :

Q stands at one extreme end and S at the other.

=> Q _ _ _ _ _ S    (or)    S _ _ _ _ _ Q

Only two persons are standing between Q and R.

=> Q _ _ R _ _ S    (or)    S _ _ R _ _ Q

Only four persons are standing between S and T.

=> Q T _ R _ _ S    (or)    S _ _ R _ T Q

V is an immediate neighbour of R and T.

=> Q T V R _ _ S    (or)    S _ _ R V T Q

Thus, the position of V can be either 5th from right end or 3rd from right end, it cannot be determined.

$$\therefore$$ Both statements even together are insufficient.
