Answer 1

The correct option is A F

A building has seven floors and seven people A, B, C, D, E, F and G lived on those floors.
A lives on fourth floor.
E lives on the floor immediately below F's floor
$\underset{–}{F}\underset{–}{E}$
F does not live on second or seventh floor
C lives on third floor, B does not live on a floor immediately above or below C's floor.
C lives on third floor, B does not live on a floor immediately above or below C's floor.

D does not live on the topmost floor. G does not live on any floor below E's floor.
It means G lives on floor any where above E's floor.
From the above given information, we conclude that
$\begin{array}{ccc}G& 7th& floor\\ F& 6th& floor\\ E& 5th& floor\\ A& 4th& floor\\ C& 3rd& floor\\ D& 2nd& floor\\ B& 1st& floor\end{array}$
F lives on 6th floor which is an even digit number and rest of the persons live on odd digit number floor.
