Question

find the compound interest on 10000 for 1 year at 8% per annum compound quarterly.​

Answer 1

$ca = p \times( {1 + \frac{r}{100} })^{2} \\ = 10000 \times ( 1 + { \frac{4}{100} })^{2} \\ = 10000 \times( 1 + { \frac{1}{25} })^{2} \\ = 10000 \times \frac{26}{25} \times \frac{26}{25} \\ = 10816 \\ ci = ca - p \\ = 10816 - 10000 \\ ans = 816$
