Because he is too short to reach the button higher than 26th floor, as the buttons on the elevator go like this. 

1 --- 26
2 ---- 27

24 --- 49
25 --- 50

Well done

 

Hey, that was it? Awesome.

 

Okay, I have a math one that's probably really easy, but if you think the wrong way, it may not be that easy. I'm not even sure it's a brain teaser. 

 

Using the 2 digit system (binary), 3 digit system, and the 5 digit system, your mission is to get 210.

The catch though, is that you must use exactly 12 digits in total over the 3 systems. 

 

If someone has a better one, add it, and we'll do that one instead, as this one is probably a bit dull to most people.
