Answer:
The effective rate of interest in the fifth year is 6.15%
Explanation:
Mathematically, the effective rate of interest can be calculated as follows;
Reff = (1 + r/y)^y - 1
where;
r is the interest rate = 6% = 6/100 = 0.06
y is the period = 5 years
Substituting these values;
Reff = (1 + 0.06/5)^5 - 1
Reff = (1 + 0.012)^5 - 1
Reff = 1.012^5 - 1
Reff = 1.061457 - 1
Reff = 0.0615 which is 6.15%
