# Valuation of Fixed-Income Securities [closed] Could one of you please assist with question 4 shown in the image above?

Bonds X and Y pay semiannual coupons. Then the cash flow for X is a single payment at the maturity of 3\$(half of 6\$ since it's semiannual) plus the par value. The discounted cash flow has to equal the price of the bond.
Then you have :$$100,98 = \frac{103}{1+R_{0.5}}$$ Solving for $R_{0.5}$ gives you 2%
Then you can perform the same calculation for Y, knowing that you have a first cash flow of 4\$(that has to be discounted with$R_{0.5}$) for the first 6-month period and a second for the second period for the coupon and the principal payment (that should be discounted with$R_1$). I wish I could "add a comment" to your answer but I can't for the moment. Of course, the coupon for Y is 4\$ I corrected my answer. However, you are missing to square the denominator (because you are discounting the cash flow of the second period). You should have : $$103.59 = \frac{4}{1+R_{0.5}} + \frac{104}{(1+R_1)^2}$$ Since you know $R_{0.5}$ you can solve for $R_{1}$.
