Question

On what sum will $Rs10.45$ be earned in $73days$ at $6\frac{1}{4}\%permonth$?

Answer 1

$$\begin{gathered} SI=Rs10.45 \\ R=6\frac{1}{4}\%=\frac{25}{4}\% \\ T=73days=\frac{73}{365}y=\frac{1}{5}y \\ P=\frac{SI\times 100}{R\times T}=\frac{10.45\times 100}{{\displaystyle \frac{25}{4}}\times {\displaystyle \frac{1}{5}}}=\frac{1045}{{\displaystyle \frac{5}{4}}}=Rs836 \end{gathered}$$
