A bank offers 6% per annum interest which is calculated and added at the end of the year. Another bank offers 10% per annum which is calculated and added every six months. What is the difference on a deposit of $100 after one year?

Answer: E

Explanation: At the bank paying 6%, the amount will be $106 ($100 * 1.06) at the end of the first year. At the bank paying 10% the amount will be $105 ($100 * 1.05) at the end of the first six months and $110.25 ($105 * 1.05) at the end of the year. Therefore the difference will be $4.25.
