Direction: Study the following information carefully and answer the question given below. Eight people P, Q, R, S, T, U, V and W are sitting around a circle. All of them are facing the center but not necessarily in the same order. P is sitting to the second of T. S is sitting next to the left of R. U is sitting opposite to W. W is sitting third to the left of P. R is neighbour of neither W nor T. R is sitting opposite to Q. V is not a neighbour of Q. Who is sitting opposite to T?

(i) Six flats on a floor in two rows facing North and South are allotted to P, Q, R, S, T and U. (ii) Q gets a North facing flat and is not next of S. (iii) S and U get diagonally opposite flats. (iv) R, next to U, gets a South facing flat and T gets a North facing flat. If the flats of T and P are interchanged, whose flat will be next to that of U?
