Question

a man invests RS 46875 at 4% per annum compound interest for 3 years .calculate the interest for the first year

Answer 1

$<b><i><font style ="orange ">principal =46875 rate =4% time(n)=3yrs annually interest of 1year amount = [tex]amount = p(1 + \frac{r}{100} )^{1}$

$46875(1 + \frac{4}{100} ) ^{1}$

$46875 \times \frac{1 \times 25 + 1}{25}$

$46875 \times \frac{26}{25}$

$9363 \times \frac{26}{5}$

$\frac{243483}{5}$

$48687.5$

$compound \: interest \: = amount - principal$

$48687.5 - 46875$

$1812.6$
