Answer:
a. 6% b. 10.40%
a. Bond price at the end of year at 6% = 104 + 1,000 / (1 + 6%) = 1104/1.06 = $1,041.51
Rate of return = (1,041.51 + 104 - 1,000) / 1,000 = 145.51/1,000 = 0.14551 = 14.55%
b. Bond price at the end of year at 10.40% = 104 + 1,000 / (1 + 10.4%) = 1104/1.104 = $1,000
Rate of return = (1,000 + 104 - 1,000) / 1,000 = 104/1,000 = 0.104 = 10.40%
