i didn't understand how it comes , can any body explain, plse go through the following link: http://www.jiskha.com/display.cgi?id=1364807092
@msingh , let us first start with your introduction with compound interest formula. Can you tell me the formula for compound interest Msingh?
yes, i know theformula for CI
What is the formula for Amount?
\(A_n = P(1+\cfrac{R}{100})^n\)
n = no. of times compounded ...
Solve A for 8% interest first [n=1 as it is compounded annualy]
See http://en.wikipedia.org/wiki/Compound_interest#Compound_Interest for a formula
the interest rate for 10% compounded semi-annually (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)
@msingh is your doubt clear now?
yeah, i have solved it ...but one thing i have doubt about this line AFTER 1 YEAR WOULD HAVE BEEN 225 MORE
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
@mathslover & @phi thank you so much
