Therefore..the elevator is on the 14th floor.

Answer 2

Given: An elevator is on 20th floor. It goes down 11 floors and then up 5 floors.

To find: The floor at which the elevator is on now.

Solution:

Since the elevator is on the 20th floor, the 11 floors must be subtracted from 20. The subtraction is supposed to be done because the elevator goes 11 floors down.

20 - 11 = 9

Hence, the elevator is on the 9th floor after going 11 floors down. Then, it goes 5 floors up. So, the 5 floors must be added to the 9 floors.

9 + 5 = 14

So the elevator is on the 14th floor after moving up the 5 floors.

Therefore, the floor which the elevator is now on the 14th floor.
