    The correct option is (b)



    Monthly payment for 6 months = $30 per month

    Time period = 6 month (6 periods)

    Monthly interest rate = 2%

    In order to compute borrowed amount, present value of these payments need to be computed which is an annuity as same amount of $30 is paid.

    Checking PVIFA table for 2%, 6 periods, annuity factor is 5.6014.

    Borrowed amount = Monthly payment * PVIFA (2%,6)

    = 30 * 5.6014

    = $168.042

    Borrowed amount is $168.042 or $168.22 approximately (difference in value due to annuity factor being rounded off)
