» Rate = 10%

» Years = 3 years

To find ,

» Simple Interest

Now , by using the formula of simple interest

$\begin{gathered}\\\; \longrightarrow{\sf{simple \: interest\;=\;\bf{\bigg(\;\dfrac{p \times r \times t}{100}\bigg)}}}\end{gathered}$

$\begin{gathered}\\\; \longrightarrow{\sf{simple \: interest\;=\;\bf{\bigg(\;\dfrac{8000 \times 10 \times 3}{100}\bigg)}}}\end{gathered}$

$\begin{gathered}\\\; \longrightarrow{\sf{simple \: interest\;=\;\bf{\bigg(\;{800 \times 3}\bigg)}}}\end{gathered}$
