Question

Find the simple interest on Rs. 12000 at 12% p.a. for 2 years.

Answer 1

$$\begin{gathered} \mathrm{P}=\mathrm{Rs}.12000 \\ \mathrm{R}=12\% \\ \mathrm{T}=2\mathrm{yrs} \end{gathered}$$

$$\begin{gathered} \mathrm{SI}=\frac{\mathrm{P}\times \mathrm{R}\times \mathrm{T}}{100} \\ \mathrm{SI}=\frac{12000\times 12\times 2}{100} \\ \Rightarrow \frac{120\times 12\times 2}{1} \\ \Rightarrow 1440\times 2 \\ \Rightarrow 2880 \\ \mathrm{SI}=\mathrm{Rs}.2880 \end{gathered}$$

Simple Interest is Rs. 2880
