Mathematically,

$\: \: \:$

$\boxed{ \bold \pink{S.I .= \frac{PRN}{100}}}$

Let's find answer for this question !

$\bold \blue{S.I .= \frac{PRN}{100}}$

$\bold \orange{S.I .= \frac{800 \times 4 \times \frac{5}{2} }{100}}$

$\bold \blue{S.I .= \frac{800 \times 20 }{200}}$

$\bold \orange{S.I .= 800 \times 10}$

$\bold \blue{S.I .= 800 0}$

$\: \: \:$

$\boxed { \fcolorbox{cyan}{teal}{ \boxed{ \bold \red{ \bold \red{ \boxed { \fcolorbox{lime}{orange}{ \boxed{ \bold \red { : \implies \bold \red{S.I .= 800 0}}}}}}}}}}$
