Answer:
6.79%
Explanation:
Use the following formula to calculate the Effective annual rate
Effective annual rate = ( ( ( 1 + Nominal return )^12 ) / ( ( 1 + Inflation return )^12 ) - 1 )
Where
Nominal rate = 0.75%
Inflation rate = 0.20%
Placing values in the formula
Effective annual rate = ( ( ( 1 + 0.75% )^12 ) / ( ( 1 + 0.2% )^12 ) - 1 )
Effective annual rate = 6.79%
