[tex] = 20000 {(1 + \frac{ 9\%}{1} )}^{2 } \\ = 20000{(1 + \frac{ 9}{100} )}^{2} \\ = 20000 {( \frac{209}{100}) }^{2} \\ = \frac{20000 \times 209 \times 209}{100 \times 100} \\ =Rs. 23762[/tex]
Answer:
Explanation:
Given :
To Find :
Solution :
Amount formula for compounded anually
[tex]\sf{Amount}=p\bigg(1+\dfrac{r}{100}\bigg)^{n}[/tex]
Substitute the values :-
[tex]\sf{A}=20000\bigg(1+\dfrac{9}{100}\bigg)^{2}[/tex]
[tex]\sf{A}=20000\bigg(\dfrac{11881}{10000}\bigg)[/tex]
[tex]\sf{A}=2\times11881[/tex]
∴ A = 23762
Compound interest (CI) formula
[tex]\boxed{\sf{CI=Amount - Principal}}[/tex]
Substitute the values
Compound Interest = 23762 - 20000
∴ CI = 3762
