    Q: The annual interest rate of a 2-month fixed deposit account was 6%,

    and that of a saving account was 4%. Mr. Lau put $35000 in a 2-month

    fixed deposit account, and he withdrew the amount 15 days after the

    deposit is mature. How much did he withdrew?

    Sol:

    35000 × ( 1 + 2 × 6%/12 )

    = 35000 × 1.01

    = 35350 ....... total amount after 2-month fixed deposite matured

    35350 × ( 1 + 15 × 4%/365 )

    = 35350 × 365.6/365

    ≒ 35408

    Ans: $35408

    35000+35000*{(6%/12)/30}15=35087.5
