Answer 2

The rate of interest is 25%

Step-by-step explanation:

Principal =Rs.5632

Amount = Rs.8019

No. of compounds per year = 2

Time=1.5 years

Formula :$A=P(1+\frac{r}{n})^{nt}$

$8019=5632(1+\frac{r}{2})^{2 \times 1.5}$

$\frac{8019}{5632}=(1+\frac{r}{2})^{3}$

$\sqrt[3]{\frac{8019}{5632}}=(1+\frac{r}{2})$

$\sqrt[3]{\frac{8019}{5632}}-1=\frac{r}{2}$

$2 \times 0.125=r$

0.25=r

25% = r

Hence The rate of interest is 25%
