Answer and Explanation:
The computation is given below:
For Bank A,
Effective annual rate is
= (1 + 0.10 ÷ 12)^12 - 1
= 10.47%
For Bank B,
Effective annual rate is
= (1 + 0.11 ÷ 4)^4 - 1
= 11.46%
And,
For Bank C,
Effective annual rate = 12%
Therefore, Bank A is best to borrow at lowest effective annual rate
