Question

aflati rata dobanzii compuse pe un an, care la un capital initial de 120000 lei genereaza in timp de 3 ani o dobândă de 87360

Answer 1

Dobanda compusa = Suma×[ ( 1+p%) ⁿ -1 ]

Suma=120 000 lei

n=3 ani

Dobanda compusa=87 360 lei

$87\ 360=120\ 000\cdot[ (1+\frac{p}{100} )^3-1]\\\\0,728=(1+\frac{p}{100} )^3-1\\\\1,728=(1+\frac{p}{100} )^3\\\\1,2=1+\frac{p}{100} \\\\0,2=\frac{p}{100} \\\\p=20\%$

Rata dobanzii compuse=20%
