⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{Simple\: Interest = Amount - Principle}}}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ Interest = Rs. 10344 - Rs. 8620 }}$

$\sf{\red{\boxed{\bold{Interest = \dfrac{Principle \times Rate \times Time}{100}}}}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ 1724 = \dfrac{ 8620\times 10\times Time}{100}}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ 1724 = \dfrac{ 8620\times Time}{10}}}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ 1724 = 862 \times time }}$

⠀⠀⠀⠀

$\sf :\implies\: {\bold{ Time = \dfrac{ 1724}{862}}}$
