Answer:
7.70%
Step-by-step explanation:
Semi-annual YTM = 9.25%/2 = 4.625%
Number of periods = 25*2 = 50 Periods
C = Coupon Amount
Price of the bond = Present Value of coupon interests + Present Value of Par Value
$850 = C*(PVIFA 4.625%, 50 Years) + $1,000*(PVIF 4.625%, 50 Years)
$850 = (C x 19.3667869) + ($1000 x 0.1042861)
$850 = (C x 19.3667869) + 104.29
$745.71 = (C x 19.3667869])
C = $745.71 / 19.3667869
C = $38.50
Coupon payment (C) = $38.50
Hence, annual Coupon Amount = $38.50 * 2 = $77.00
Bond Nominal (annual) Coupon Interest Rate = (Annual Coupon Amount / Par Value) x 100
Bond Nominal (annual) Coupon Interest Rate = ($77.00 / 1,000) x 100
Bond Nominal (annual) Coupon Interest Rate = 7.70%
