Answer 1

$\huge{\fbox{\blue{\fbox{\red{Given}}}}}$

Principal = ₹ 2000

Rate = 5%

Time = 2 years

$\huge{\fbox{\blue{\fbox{\red{Solution}}}}}$

$\sf{Amount\: =\: P\bigg(1\: +\: {\dfrac{r}{100}}\bigg)^n}$

$\sf{\implies\: Amount\: =\: 2000\: \times\: \bigg(1\: +\: {\dfrac{5}{100}}\bigg)^2}$

$\sf{\implies\: Amount\: =\: 2000\: \times\: {\dfrac{105}{100}}\: \times\: {\dfrac{105}{100}}}$

$\sf{\implies\: Amount\: =\: \bold{2205}}$

Compound interest = Amount - Principal

= ₹(2205 - 2000)

= ₹ 205
