Given:
Principal amount = $2000
Interest rate = 12%
Find-:
(a) Amount in an account at the end of 1 year
(b)Amount in an account at the end of 2 year
Sol:
Compounded interest rate is:
![A=P(1+\frac{r}{n})^{nt}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D)
(a)
Amount after 1 year is:
![\begin{gathered} t=1 \\ \\ r=\frac{12}{100} \\ \\ r=0.12 \\ \\ n=1 \\ \\ P=2000 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20t%3D1%20%5C%5C%20%20%5C%5C%20r%3D%5Cfrac%7B12%7D%7B100%7D%20%5C%5C%20%20%5C%5C%20r%3D0.12%20%5C%5C%20%20%5C%5C%20n%3D1%20%5C%5C%20%20%5C%5C%20P%3D2000%20%5Cend%7Bgathered%7D)
So the amount is:
![\begin{gathered} A=2000(1+\frac{0.12}{1})^{1\times1} \\ \\ A=2000(1.12) \\ \\ A=2240 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3D2000%281%2B%5Cfrac%7B0.12%7D%7B1%7D%29%5E%7B1%5Ctimes1%7D%20%5C%5C%20%20%5C%5C%20A%3D2000%281.12%29%20%5C%5C%20%20%5C%5C%20A%3D2240%20%5Cend%7Bgathered%7D)
After one year amount in the account is $2240
(b)
Amount after two years is:
![\begin{gathered} t=2 \\ \\ n=1 \\ \\ r=0.12 \\ \\ P=2000 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20t%3D2%20%5C%5C%20%20%5C%5C%20n%3D1%20%5C%5C%20%20%5C%5C%20r%3D0.12%20%5C%5C%20%20%5C%5C%20P%3D2000%20%5Cend%7Bgathered%7D)
So amount is:
![\begin{gathered} A=P(1+\frac{r}{n})^{nt} \\ \\ A=2000(1+\frac{0.12}{1})^{1\times2} \\ \\ A=2000(1.12)^2 \\ \\ A=2000\times1.2544 \\ \\ A=2508.8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20A%3DP%281%2B%5Cfrac%7Br%7D%7Bn%7D%29%5E%7Bnt%7D%20%5C%5C%20%20%5C%5C%20A%3D2000%281%2B%5Cfrac%7B0.12%7D%7B1%7D%29%5E%7B1%5Ctimes2%7D%20%5C%5C%20%20%5C%5C%20A%3D2000%281.12%29%5E2%20%5C%5C%20%20%5C%5C%20A%3D2000%5Ctimes1.2544%20%5C%5C%20%20%5C%5C%20A%3D2508.8%20%5Cend%7Bgathered%7D)
After two years amount in the account is $2508.8
