Ad libitum [116K]

The answer to this question would be B. Mystic


Since the rate should be constant, option C and D wouldn't be true.
If the Four Rivers bank gives 12% per year and Mystic Bank gives 14% per year, it will be 3% per quarter year for Four Rivers Bank and 7% semiannually for Mystic Bank.
The total rate would become:
Four rivers 103%^4= 1.125
Mystic : 107%^2= 1.145
