In elevator is on the 20th floor it goes down 11 floors and then up five floor is what floor is the elevator on now
To determine the current floor of the elevator, we need to calculate the net change in the number of floors.
The elevator started on the twentieth floor, so we can imagine it is initially at floor 20.
It goes down 11 floors, which means we subtract 11 from the initial floor:
20 - 11 = 9
Now the elevator is on the ninth floor.
Then it goes up 5 floors from the current floor:
9 + 5 = 14
Therefore, the elevator is currently on the 14th floor.
