Step-by-step reasoning process: Earl was on the 1 + 5 = 6th floor after going up 5 floors. When he went down 2 floors, he was on the 6 - 2 = 4th floor. Since he went up 7 floors, he was then on the 4 + 7 = 11th floor. Since he is 9 floors away from the top of the building, therefore the building has 11 + 9 = 20 floors.
