Question a sum of money is invested at a half yearly compound interest rate of 5%. if the difference of principal at the end of 6 months and 12 months is $ 126 find the sum of money invested and also find the amount at the end of 1 1/2 (one and a half) years
Answer FV = P(1 + r/n)^t*n
P unknown
r = 0.05
n = 1
t = 1
(Since the interest rate is given in half yearly compound interest rate, the time unit of t = 1 is 6mo.)
