    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
