Formula 1 Let P be the principal and the rate of interest be `R%` per annum. If the interest is compounded annually then the amount A and the compound interest C.I. at the end of n years are given by `A=P(1+R/100)^n and C.I. = A-P=P{(1+R/100)^n-1}` respectively.

Formula 2 Let P be the principal and the rate of interest be R% per annum.If the interest is compounded annually then the amount A and the compound interest C.I.at the end of n years are given by A=P(1+(R)/(100k))^(nk) and C.I.A-P=P{((1_(R))/(100k))^(nk)-1} respectively

Find the compound interest on Rs 5000 at 10% per annum for 1 year, interest compounded annually?

Let P be the principal and the rate of interest be R_1 % for first year R_2 % for second year R_3 % for third year and so on and in the last R_n % for the nth year. Then the amount A and the compound interest C.I. at the end of n years are given by A=P(1+R_1/100) (1+ R_2/100) ...... (1+ R_n/100) and C.I. =A-P respectively.
