A = P( 1 + r/n)^nt
where n is the number of compounding a year
⇒A = 3000(1 + 0.1/2)^(2×2)
      = 3000× (1.05)^4
      = 3646.52

Principal=3000rs
interest=10% compounded semi annually
time =2yrs
amount=p(1+r/200)^2t
=3000(1+10/200)^4
=3000*21/20*21/20*21/20*21/20
=3000*194481/160000
=3654.02
compound interest =amount - principal
= 3654.02-3000
=654.02 ans
