The Man in the Elevator

For a start, here’s one of the oldest and
best-known lateral thinking problems. It
goes like this:
The Man in the Elevator

A man lives on the tenth floor of a
building. Every day, he takes the
elevator to the first floor to go to work.
When he returns, he always takes the
elevator to the seventh floor and then
walks the remaining flights of stairs to
his apartment on the tenth floor. Why
does he do this?


Ask yourself:
Is there anything he does between
the seventh and tenth floors other
than climb the stairs?

If he had someone else with him,
would they both get out at the 7th
floor and walk up to the tenth?
No
The Man in the Elevator
If he lived on the sixth floor, would he
go up to the sixth floor in the elevator?
Yes
 If he lived in a different block of
apartments in a different country but
still on the 10th floor, would he still get
out on the 7th floor when going up?
Most probably yes.

