Suppose you have the choice of investing in (A) a zero-coupon bond, which costs $500 today, pays no coupon during its life, compounds semi-annually, and then pays $1,000 after 10 years, or (B) a bond which costs $1,100 today, pays $45 in interest semi annually, and matures at the end of 10 years. What are the Semi-Annual yields to maturity of the two bonds?
