Answer 2

$\mathfrak{Step-By-Step\:Explanation:}$

Given :

• Principle = Rs. 2500.
• Time = 2 years.
• Rate = 8% p.a.

We know that ,

$\boxed{\bold{Amount=Principle\left(1+\dfrac{r}{100}\right)^n}}\\\\\\\tt{=2500\left(1+\dfrac{8}{100}\right)^2}\\\\\\\tt{=2500\left(1+\dfrac{2}{25}\right)^2}\\\\\\\tt{=2500\times \dfrac{27}{25}\times \dfrac{27}{25}}\\\\\\\tt{=Rs.2916.}\\\\\\\boxed{\bold{CI=Amount-Principle}}\\\\\\\tt{=2916-2500}\\\\\\\tt{=416.}\\\\\\\boxed{\boxed{\bold{Compound\:Interest=Rs.\;416.}}}$
