  • Principle = Rs. 6400.
  • Rate = 12%.
  • Time = 2 years.

[tex]\boxed{\bold{Amount=Principle\left(1+\dfrac{r}{100}\right)^n}}\\\\\\\tt{=6400\left(1+\dfrac{12}{100}\right)^2}\\\\\\\tt{=6400\left(1+\dfrac{3}{25}\right)^2}\\\\\\\tt{=6400\times \dfrac{28}{25}\times\dfrac{28}{25}}\\\\\\\tt{=10.24\times 784}\\\\\\\tt{=8028.16}\\\\\\\boxed{\bold{CI=Amount-Principle}}\\\\\\\tt{=8028.16-6400}\\\\\\\tt{=1628.16}\\\\\\\boxed{\boxed{\bold{CI=Rs.\;1628.16}}}[/tex]
