Solution(By Apex Team)
$\begin{array}{l}
\mathrm{t}=1 \text { month }=\frac{1}{12} \text { year } \\
\mathrm{SI}=1 \text { paisa }=\text { Rs. } \frac{1}{100} \\
\mathrm{r} \%=\frac{\mathrm{SI} \times 100}{\mathrm{P} \times \mathrm{T}}=\frac{1 \times 100 \times 12}{100 \times 1 \times 1} \\
\mathrm{r} \%=12 \%
\end{array}$
