Simple. I assume the ones going to the middle school are currently in 5th grade at the elementary school. You have 126 coming into the middle school from each school. You need to multiply 126 by 4. You get 504. There will be 504 new students at the middle school.
Kovalf was a committee-man. He had been one for two years and he couldn't take that out of his own head. This only shows how much the Russian society used to value their titles back then and this might actually be true today.
Kovalf could never forget that he was once a committee-man, therefore to boost his own importance, even to himself, he started calling himself "Major".
