It is not too clear "current" means 2014 or 2015. Will assume baseline year to be 2015 when 20 more schools are built.

Number of students in 2015=1200
Number of students in 2016=1200*1.2=1440

Teacher:student ratio in 2015=1:60
Number of teachers in 2015=1200/60=20

Teacher:student ratio in 2016=1:30
Number of teachers in 2016=1440/30=48

Number of additional teachers required
= 48-20
=28
