This Exam FM sample reference tests Spot and Forward Rates. A zero NPV at 4% means the original 4,000 must grow to the same year-3 value as the three receipts reinvested at i. Solving the resulting quadratic gives positive rate 6.97%, so choice E is correct.
These notes identify the calculation error associated with each wrong letter when that error is reproducible.
AChoice A (2.5%) does not satisfy the equality of the year-3 accumulated cost and reinvested receipts; no distinct standard one-step error is identifiable.
BChoice B (3.0%) does not satisfy the equality of the year-3 accumulated cost and reinvested receipts; no distinct standard one-step error is identifiable.
CChoice C (3.5%) does not satisfy the equality of the year-3 accumulated cost and reinvested receipts; no distinct standard one-step error is identifiable.
DChoice D (4.0%) does not satisfy the equality of the year-3 accumulated cost and reinvested receipts; no distinct standard one-step error is identifiable.

Original variant: final receipt required for a target terminal-value return
An investment costs 5,000 today and pays 1,200 at year 1 and 1,500 at year 2. Those receipts can be reinvested at 5%. Calculate the year-3 receipt required for the investment to earn a 6% annual terminal-value return over three years.
A 2,598.52
B 2,751.37
C 2,904.23
D 3,057.08
E 3,209.93
Variant answer in brief
The target year-3 fund is 5,955.08. After crediting the reinvested first two receipts, the required final receipt is 3,057.08, choice D.
Setup
Setup
Accumulate the original cost at the target return to obtain the required year-3 wealth.
F∗=5000(1.06)3
Model
Model
Accumulate the first receipt for two years and the second for one year at the available reinvestment rate.
F∗=1200(1.05)2+1500(1.05)+X
Compute
Compute
Solving the terminal balance gives final receipt 3057.08.
X=5000(1.06)3−1200(1.05)2−1500(1.05)=3057.080000
Answer
Answer
The year-3 receipt must be 3,057.08, which is choice D.
