I think 26 floors because 12+10=22-7=15.If it is 15, then it will be two floors above the middle of the building. Then it may be 13.If it is please click on like,follow and mark brainliest.

Answer:
there are 26 floors
Step-by-step explanation:
first he goes to 12th floor.
he then goes 10 floors up which is 22nd floor.
he then comes 7 floors down which is 15th floor.
he finds that he is 2 floors above the middle of the building, therefore the middle of the building is 13th floor.
total number of floors =half of the floors multiplied by 2.
therfore the answer is 13*2=26
therefore there are 26 floors in the building.
hence proved
