Question

A building has the same number and size of rooms on each floor. If there are 10 offices on the first 2 floors, then what is the total number of rooms in the 5 story building?

Question 14 options:

10


20


25


30

Answer 1

So there are 10 offices in the first 2 floors
All the stories of the building have the same amount of offices on each floor
to see how many are on one floor
10 / 2
That is there are 5 offices on each floor

If there are 5 floors
then... 5+5+5+5+5
or 5*5
There are a total of 25 rooms in a 5-story building.

Hope this helps :)
