Answer
$ 10.52\%$
Work Step by Step
The effective interest rate $r_{eff}$ of an investment$\\$
paying a nominal interest rate of $r_{nom}=10\%=0.10\\\\$
compounded m$=365 \ \ \ \ $ times per year is$\\$
$r_{eff}=(1+\displaystyle \frac{r_{nom}}{m})^{m}-1$
$=(1+\displaystyle \frac{0.1}{365})^{365}-1\approx$0.105155781616$\\\\$
Rounded to the nearest $ 0.01\%$ (4th decimal place):
$ r_{eff}=10.52\%$
