​

Answer 1

Let the salary of ramu be x

Then 20% increase in salary =20/100*x=x/5

New salary=x+x/5=6x/5

Salary decreased by 30%=30/100*6x/5=9x/25

Ramu New salary=6x/5-9x/25

=30x-9x/25

=21x/25

Now according to the question,x - 21x/25

=8560

25x-21x/25=8560

4x/25=8560

x=8560*25/4

x=53,500

Hence ramu's original salary is 53,500
