Solution:

8
new n/w,20 is already employed

total n/w=20+8=28n/w

so that 75% came from same university then 28*75/100=21

we all know 8 n/w is recently hired then 21-8=13

so that the fraction is=13/20

total n/w=20+8=28n/w

so that 75% came from same university then 28*75/100=21

we all know 8 n/w is recently hired then 21-8=13

so that the fraction is=13/20
