⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{Amount = Principle \bigg\lgroup 1 + \dfrac{r}{100}\bigg\rgroup ^{time}}}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 200 \bigg\lgroup 1 + \dfrac{10}{100}\bigg\rgroup^{2}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 200 \bigg\lgroup 1 + \dfrac{1}{10}\bigg\rgroup^{2}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 200 \bigg\lgroup \dfrac{10 + 1 }{10}\bigg\rgroup^{2}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 200 \bigg\lgroup \dfrac{11}{10}\bigg\rgroup^{2}}}$

⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 200 \times\dfrac{11}{10}\times \dfrac{11}{10}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 20 \times\dfrac{11}{10}\times {11}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 2\times{11}\times{11}}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = 2\times 121}}$

⠀⠀⠀⠀⠀⠀⠀⠀

$\sf :\implies\:{\bold{ Amount = Rs. 242}}$

⠀⠀⠀⠀⠀⠀⠀⠀

$\sf{\red{\boxed{\bold{CI = Amount - Principle}}}}$

⠀⠀⠀⠀⠀⠀⠀⠀

$\sf :\implies\:{\bold{CI = Rs. 242 - Rs. 200}}$

⠀⠀⠀⠀

$\sf :\implies\:{\bold{CI = Rs. 42}}$
