2nd problem:

A teacher received 5 more files. 45 - 9=36,which is the number of techers who got 5 more files.36 x 5=180, which is the total number of files the nine teachers gave away.180/9=20,which is the number of files each teacher got originally. So, 45x20=900, which is the number of files the school bought.

Ans:900
