    A solved question from MIT:

    If the nominal interest rate is 20% per year, how much money can an individual borrow for a year if she wants to repay $100 (total, i.e. in both principal and interest) in one year?

    A) $80.00
    B) $83.33
    C) $120.00
    D) $78.00
    E) $121.00


    http://web.mit.edu/14.02/www/S01/s01_quiz2soln.pdf
    (Page 3, Question 1)

    100 / (1 + 20%) = $83.33
    ---
    Principal + Interest = 100
    Principal + Principal·20 / 100 = 100
    Principal·(1 + 1 / 5) = 100
    Principal·6 = 500
    Principal = 500 / 6 = 250 / 3
    Principal = $83.33
    ---
    Notes for the students:
    The underlined word has been mistakenly printed as "principle" in the original question.
