First by simple interest we will find principal.
SI =prt is the formula
let p be x
x*5/100*3=540
x*5/100=540/3
x*5/100=180
x*5=180*100
x*5=18000
x=18000/5
x=3600
Now amount than compound interest
amount =p(1+r/100)power time
=3600(1+5/100)power 3
=3600*21/20*21/20*21/20
=4167.45
Now compound interest
CI=A-p
CI=4167.45-3600
=567.45
Hope it will help you.
