This Exam FM sample reference tests Rate Conversion in an Annuity. The conversion-period condition implies an annual accumulation factor of 1.0614 regardless of m. Solving a-angle-n at 6.14% equal to 5.5554 gives n = 7, choice A.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
BChoice B treats 6.14% as the nominal rate before conversion rather than the annual effective rate already implied.
CChoice C values the annual payments at the conversion-period rate j without knowing or needing m.
DChoice D divides 6.14% by a guessed conversion frequency and extends the annuity term.
EChoice E overlooks that the given power fixes the annual effective rate, so m is not needed.

Original variant: value an annual annuity from a conversion condition
A nominal rate is convertible m times per year, with conversion-period rate j satisfying one plus j to the m equal to 1.08. Determine the present value of nine annual payments of 1 made at year-end.
A 5.9982
B 6.1104
C 6.2469
D 6.5152
E 7.2469
Variant answer in brief
The power condition gives an 8% annual effective rate. Nine year-end payments have present value a-angle-9 at 8%, equal to 6.2469, choice C.
Setup
Setup
The conversion condition is already the one-year accumulation factor.
