Solution
\sf{\red{\boxed{\bold{Interest = \dfrac{P \times R \times T}{100}}}}}
Interest=
100
P×R×T
⠀⠀⠀⠀
\sf : \implies\: {\bold{ 450 = \dfrac{P\times 5 \times 3 }{100}}}:⟹450=
100
P×5×3
⠀⠀⠀⠀
\sf : \implies\: {\bold{ 450 = \dfrac{P\times 3 }{20}}}:⟹450=
20
P×3
⠀⠀⠀
\sf : \implies\: {\bold{ P = \dfrac{450\times 20 }{3}}}:⟹P=
3
450×20
⠀⠀⠀⠀
\sf : \implies\: {\bold{ P = 150 \times 20 }}:⟹P=150×20
⠀⠀⠀⠀
\sf : \implies\: {\bold{ P =Rs. 3000}}:⟹P=Rs.3000
