$\large{\underline{\red{\rm{AnswEr:1155}}}}$

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

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

• Principal=₹1000
• Time=2 years
• Rate 1=10%
• Rate 2=5%

$\bold\orange{\underline{Find: Amount\:due\:in\:2\: years}}$

Note:If the rate of interest for successive year is R¹ R² R³ and so on.

• Using formula here

$\bold\purple{\boxed{Amount=P(1+\frac{r1}{100})(1+\frac{r2}{100})}}$

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

⟹Amount={1000(1+10/100)(1+5/100)}

⟹Amount={1000(100+10/100)(100+5/100)}

⟹Amount=1000*110/100*105/100

⟹Amount=11*105

⟹Amount=₹1155

Hence,

The amount due in 2 years is ₹1155
