$\large{\underline{\red{\rm{AnswEr:3400.9564}}}}$

$\huge\bold\red{\underline{Solution:}}$

$\bold\green{\underline{Given:}}$

• Principal=10000
• Rate=10%
• Time=3 years

$\bold\green{\underline{Find:}}$

• Compound Interest:

$\bold\orange{\underline{A.T.Q}}$

• using formula here

$\bold\purple{\boxed{CI=P(1+\frac{r}{100})^n-P}}$

Note:If Compounded half yearly than we have to change r and t

• Rate=r/2=10/2=5%
• Time=t×2=3×2=6 year's

⟹CI=10000(1+5/100)^6-10000

⟹CI=10000(21/20)^6-10000

⟹CI=10000×1.34009564-10000

⟹CI=13,400.9564-10000

⟹CI=3,400.9564

Hence,

$\bold\green{\boxed{Compound\: Interest=3400.9564}}$
