number of half years=3
rate is mentioned in terms of per annum
thus it needs to be halved.
so, r= 12.5/2=6.25% or 25/4% per half yearly
amount=p(1+r)^t
=8192(1+25/400)^3
=8192(17/16)^3
=4096*2(17^3)/4096 (since 8192=4096*2 and 16^3 =4096)
=2*17^3=rs9826

Why Shall Dravid be paid the amount, when its just WE who are investing that amount?
