the difference between the compound interest and simple interest for 2 yearsmay be arrived in the form PxRXR/10000.
R=8,solving get P=2500
Simple interest for the amount=400
comp interest =416
comp interest half-yearly =424.65
hence difference =24.65

the sum is:
16/(1.08*1.08-1.16)=2500

the difference between simple and half yearly interest:
2500(1.04^4-1.16)=25

solution is o.k. The explanation is as under when r=0.08
p*(1.08^2-1.16)=16 gives p=2500 when compounded yearly and when compounded half yearly difference in interest is 2500*(1.04^4-1.16) that comes Rs. 24.6464 say Rs 24.65
