Respuesta :
The effective interest rate is greater by 0.72 percentage points as compared to the nominal interest rates.
Computation:
Given,
[tex](r)[/tex] Nominal Interest rate =11.85%
[tex](m)[/tex] compounding period = weekly, that is 52.
The formula of the effective interest rate will be used:
[tex]\begin{aligned}\text{Effective Interest Rate}&=(1+\frac{r}{m})^m-1\\&=(1+\frac{0.1185}{52})^{52}-1\\&=(1.00227)^{52}-1\\&=0.1257\;\text{or}\;12.57\%\end{aligned}[/tex]
Now, the difference of the effective interest rate and nominal interest rate will be determined to know the exceeding percentage:
[tex]\begin{aligned}\text{Difference Percentage}&=\text{Effective Interest rate - Nominal Interest rate}\\&=0.1257-0.1185\\&=0.72\end{aligned}[/tex]
Therefore, option a. 0.72 percentage points is correct.
