    Hi wanted to know how has the risk free return been calculated in this question.

    Ideally its a discounting of the capital plus the discounting of the cashflows...

    Somehow the solution provide for the calculation (especially) of the cashflow discounting is not making sense.. it should be {P*(1 - v^10)}/ (1-v)... however the solution says its {P * ( 1 - v^10)} / l???

    Kindly suggest and guide..

    Hello

    It looks like what you're reading as "1" at the end of the formula in the solution is actually "i".

    I think this then makes the solution ok - the 37.5 coupon is multiplied by a 10 annuity factor. The formula for a 10 year annuity factor (in arrears) does divide the (1-v^10) term by i%.

    Best wishes
