Answer: The bond with the 8% coupon and a 10% current yield.
Step-by-step explanation:
When a bond has a coupon rate that it less than the yield, it is said to be a discount bond because it will be trading at a price that is less than its par value. The first bond will therefore be trading at a price lower than its par value.
The second bond however, is a premium bond. It will be trading at a price that is higher than its par value because that is what bonds so when their coupon rate is higher than their yield.
The first bond will therefore b cheaper because:
First Bond < Par < Second bond
