OK. Here is what is going on.
A man lives in an apartment located in the nineth floor (the apartment block has 11 floors, ground to tenth).
Every day, when he goes to work he takes the elevator to the lobby, but when he returns, he takes the elevator to the fifth floor and then he uses the stairs to go back to his apartment.
The question is, why the man uses the stairs?
