Answer:

The answer to your question is 14 floor

Step-by-step explanation:

To solve this problem start from the end changing the sense if it says up, then consider the action as down, etc.

Last floor = 12

Go down 4 floors = 12 - 4 = 8

Go up 8 floors = 8 + 8 = 16

Go down 2 floors = 16 - 2 = 14    

Conclusion

At the beginning I was on the 14 floor
