Could you calculate this?
(a simple task)
There is a nine floor tall building.
At every floor there are three apartments.
Every apparment has two people living inside, except the fifth floor where the number of people is greater than the number of people on a fourth flour by one. On the 7th floor the number of people is lesser than on the fifith flour by one, but greater than on the 6th flour by two.
At the 9th flour one apartment is empty, but the number of persons living on the floor is no less than at the 8th flour.
The question is - what button in the lift are being hit the most, if all the people living in the building go inside and outside of their appartments twice a day?
