years. What is the yield to maturity?

Given Face value = $ 1000
Market price = $ 974
Let Coupon rate be 2X %
Semi Annual coupon amount = $ 1000*2X%/2
= $ 10X
Duration = 15 years
No.of Coupons received = 15*2=30
YTM = 4.03%
Haly yearly YTM = 4.03% /2
= 2.015%
We know that
At YTM, Sum of the discounted value of future cash inflow is equal to the Market price of the bond

| 1000 | 0.5496 | 549.6 | |
| Total | 223.503X+549.6 | 
By solving the Equation we get
223.503X+549.6 = $ 974
223.503X = $ 974-$ 549.6
223.503X = $ 424.4
X = $ 424.4/223.503
= 1.898855%
2X ( YTM) = 1.898855*2
= 3.79771
Option A) 3.80 % is the correct answer
Part B
We know that
At YTM, Present value of future cash inflows is equal to the market price of the bond
