12 teachers to 48 teachers.

1. If you mean that number of teachers increased from 48 to 60 (48+12) then - 

% increase = ((60-48)/48)*100 %

                     = (12/48)*100 %

                      = 25% increase

2. If you mean that number of teachers increased from 12 to 48 then - 

% increase = ((48-12)/12)*100 %

                = 300% increase

Let me know if you need further help.
