Question

If the flats of $T$ and $P$ are interchanged, whose flat will be next to that of $U$ ?

• A. $Q$
• B. $T$
• C. $P$
• D. $R$

Answer 1

The correct option is D $R$

It can be deduced from the conditions given that when U is assigned a South facing flat, having S as diagonally opposite, that means S is assigned a North facing flat not adjacent to Q. And T is also assigned a North facing flat and T is between Q and S. So Q, T and S are in the same row in north facing flats.
As U and S are diagonally opposite, U is in the South facing flat with R next to it. Only P is left, thus P is also south facing flat.
So, diagonally opposite are U and S and Q and P.
Even on interchanging the of T and P, R remains next to U.
Answer is Option D.
