Could someone show me what to calculate to get the percentage below?

1. N=182=36PMT=9.735%1000/2=48.675I/Y=7.95%/2=3.975%FV=1000 CPT PV=$1,169.34 2. N=52=10 PMT =9.735%1000/2=48.675 FV=1000(1+13.5%)=1135 PV=1169.34 CPT I/Y=2.893% Could someone show me how we came up with this percentage? Hence, realized yield =2.893%2=5.786% 3. As yield to call is less than yield to maturity the bond will be called and the bondholder will expect to earn 5.786%
