Answer 1

B. 25

Answer 2

So if he's the 13th of something, there must be 12 people before or after him. Since he's the 13th highest, there are 12 people ahead of him. 13th lowest, must be 12 behind him there too. So you add up all those people and get 24, but then add him, you get 25, which is everybody in the class.
