Answer 2

Finding total amount:

Step-by-step explanation:

$\ Given \ that:\\\\\ Principle \ = \ 16000\\\\\ Time \ = \ 9 \ months \\\\\ total \ time \ =\ 3 \ quarters\\\\\ Rate \ = \ 20\% \ per \ annum \ = \ 5\% \ per \ quarter\\\\\ Solve: \\\\\ formula: A = P(1 + \frac{r}{n})^{nt}\\\\\rightarrow A=16000\times((1+(\frac{5}{100}))^3)\\\\\rightarrow A=16000\times(1+\frac{1}{20})^3\\\\\rightarrow A=16000\times(\frac{20+1}{20})^3\\\\\rightarrow A=16000\times(\frac{21}{20})^3\\\\\rightarrow A=16000\times\frac{21\times21\times21}{20\times20\times20}$

$\rightarrow A=16000\times\frac{9261}{8000}\\\\\rightarrow A=2\times9261\\\\\rightarrow A=18522$

$\ Total \ amount \ is \ = 18522$
