Answer 2

$\bf \: As \: we \: know \: that :$

$\longrightarrow \: \underline{ \green{ \boxed{ \red{\bf \: SI = \dfrac{P \times R \times T}{100} }} }}$

$\bf \: Putting \: the \: values \: :$

$\bf \: \longrightarrow \: SI = \dfrac{300 \times 5 \times 1}{100}$

$\bf \: \longrightarrow \: SI = \dfrac{3 \times 5 \times 1}{1}$

$\bf \: \longrightarrow \: SI = 3 \times 5 \times 1$

$\large \boxed{ \purple{\bf \: \longrightarrow \: \boxed{ \sf \green{ SI = 15}}}}$
