A math professor was staying in a hotel before attending a math conference. When he came out of his room, to go to the conference, he found out that the total of room numbers to his left was equal to the total of room numbers to his right. The total numbers of rooms per floor were about 300 and just assume that they are in line. The room numbers were given without skipping any number(even 13 :rofl: ) How many rooms are there in the hotel floor and in which room did the professor stay? It is damn easy solving with any of the computer programs. I did it in VB and excel(Also without these programs. By saying this I am not acting smart but just encouraging you guys). But there is a clue for getting the numbers by which you can skip all unnecessary numbers. Go get it.
