$$\begin{gathered} \begin{array}{l}\mathrm{P}=\mathrm{Rs}.1500,\mathrm{R}=\mathrm{12}\mathrm{\%},T=3+\frac{3}{12}=\frac{13}{4}\mathrm{years}\\ \mathrm{S}\mathrm{.I}.=\frac{\mathrm{P\times R\times T}}{\mathrm{100}}\mathrm{=}\frac{\mathrm{1500\times 12\times 13}}{\mathrm{100\times 4}}\\ =\mathrm{Rs}\mathrm{.\; 585}\\ \mathrm{Amount=P+S}\mathrm{.I}.\end{array} \\ =1500+585 \\ =Rs\mathrm{.\; 2085} \end{gathered}$$
