Answer 1

Answer:

Step-by-step explanation:

\begin{gathered} Principal (P)=Rs\:4500,\\Rate\:of\: interest (r)=5\%,\\Time(T)=2\: years,\\Let,\:the \: Amount = A\end{gathered}

Principal(P)=Rs4500,

Rateofinterest(r)=5%,

Time(T)=2years,

Let,theAmount=A

\boxed {A=P\left(1+\frac{RT}{100}\right)}

A=P(1+

100

RT

)

\begin{gathered}\implies A = 4500\left(1+\frac{5\times 2}{100}\right)\\=4500\left(1+\frac{1}{10}\right)\\=4500\times \left(\frac{10+1}{10}\right)\\=4500\times \frac{11}{10}\\=450\times 11\\=Rs\:4950\end{gathered}

⟹A=4500(1+
