here ur answer hope its right

Answer 2

Hey here is your Answer

GIVEN ;-

principle = 25,000 rs.
Time = three years
rate = 3% per annum

To find ;- compound interest

So, lets come to answer

First we have to find the amount .

So, as we all know the formulae :-

$a \: = p(1 + \frac{r}{100} {)}^{t}$

so, put all the values of principle, rate , year in this equation :-

$a \: = p(1 + \frac{r}{100} {)}^{t} \\ \\ a \: = 25000(1 + \frac{3}{100} {)}^{3 } \\ \\ a \: = 25000 \times ( \frac{103}{100} {)}^{3} \\ \\ a \: = 25000 \times \frac{103}{100} \times \frac{103}{100} \times { \frac{103}{100} } \\ \\ a \: = 25 \times {103} \times \frac{103}{10} \times \frac{103}{100} \\ \\ a \: = \frac{27318175}{1000} \\ \\ \bf \: a \: = 27318.175 \: rs \: \: \: answer$

Now as we all know that :-

compound interest = amount - principle
compound interest = 27318.175 - 25000 rs

$\bf \: compound \: interest \: = \\ \bf \: 2318.175 \: rs \: answer$

hope this helps you
