Answer:
The correct answer is option (E).
Explanation:
According to the scenario, the given data are as follows:
Yield rate = 4.8%
Tax rate = 27%
So, we can use the following formula to calculate the interest rate :
= Yield rate / ( 1 - tax rate)
= 4.8% / (1 - 27%)
= 0.048 / ( 1 - 0.27)
= 0.048 / 0.73
= 0.06575
= 6.58%
