Solution

Let the original salary be x
then
after increasing it by 20%
salary=x+x×20/100
=x(1+.2)=1.2x
then 30% of it is decreased
then the salary is
1.2x-1.2x×30/100
=x(1.2-.36)
=.84x
given that the effective change is 8560
that is
x-.84x=8560
that is .16x=8560
x=53500
so his original salary=x=53500
