This Exam FM sample reference tests Bond Book Value versus Market Value. Book value continues on the acquisition yield basis of 4% per half-year, not the new 3% market yield. Discounting 10 coupons of 35, then 30 coupons of 45 and redemption gives 1017.85, choice C.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
AChoice A keeps the 35 coupon for all forty remaining periods and ignores the scheduled increase.
BChoice B changes to the 45 coupon immediately after coupon 20 instead of after coupon 30.
DChoice D is approximately the market value obtained at the new 3% half-year yield; market value is not the requested amortized book value.
EChoice E combines the new market yield with the original book-value coupon amortization schedule inconsistently.

Original variant: value immediately before the next coupon
A twelve-year 1,000 redemption-value bond pays annual coupons of 40 in years 1 through 6 and 70 in years 7 through 12. At a 5% annual yield, determine the bond's value immediately before the year-5 coupon is paid.
A 1,033.48
B 1,073.48
C 1,087.16
D 1,127.16
E 1,143.83
Variant answer in brief
Immediately after the year-4 coupon, the remaining cash flows are worth 1073.4819. Accumulating one year to just before the year-5 coupon gives 1127.1560, choice D.
