8 persons- P to W live in the same building. The building
has 6 floors and each floor has two flats. Each of the
floors has the same construction, so the flats can also be
said to be stacked in two columns. At least one of them
resides on each of the floors and exactly one of them
resides in each flat. Each of them had watched movie
Deadpool, but the number of times they watched it was
distinct, with 2 being the least and 9 being the highest
number of times watched by any one. It is also known
that: P, who watched Deadpool two more time than that
of S, lives on a floor just above that of U and along the
same column of the building. None among T and W is
along the same column of the building as that of V.
The one who watched Deadpool 8 times lives on a floor
alone in the building. The total number of times Deadpool
watched by the persons living at the top floor is 10. W and
V don’t live on two consecutive floors. No one lives on the
floor of R, who has watched Deadpool 7 times. No two
flats on the consecutive floors in the same column are
vacant. Q’s and S‘s flats are in the same column, and Q
lives at least two floors above that of S. The number of
floors between V’s flat and S‘s flat is same as the number
of floors between R’s and V’s flat, but are not on
consecutive floors to each other. The number of floors
between T’s and R’s flats is same as the number of floors
between W’s and U’s flat. If A lives below the floor of V,
then P definitely does not live alone on a floor.
