the interest rate for 10% compounded semiannually (i.e. twice a year) means you use rate= 0.10/2 the number of compoundings in one year is 2, so the formula is P (1+ r/(100*2))^(2*1) or P (1+0.05)^2

the amount of principal plus interest for 8% compounded annually for one year is just P(1+0.08)^1 or P(1+0.08)

if you had compounding monthly, for n years it would be P(1+r/(100*12))^(12*n)

yeah, i have solved it ...but one thing i have doubt about this line AFTER 1 YEAR WOULD HAVE BEEN 225 MORE

mathsloverBest ResponseYou've already chosen the best response.2
It means you have X apples today then after 1 year you will have 225 + X apples. I just gave you an example.

On the place of apples, we are talking about amount here. Welcome msingh
