Answer:
8.09%
Explanation:
the coupon paid by each bond = $1,000 x 8% = $80
the net amount of money received from each bond = $990
n = 20
now we must find the yield to maturity:
YTM = {coupon + [(face value - market value)/n]} / [(face value + market value)/2]
YTM = {$80 + [($1,000 - $990)/20]} / [($1,000 + $990)/2] = $80.50 / $995 = 0.0809 = 8.09%
