Answer:
6.06%
Step-by-step explanation:
The computation of the rate of return is shown below:
Given that
NPER = 20 years
PV = ($280,000 - $80,000) = $200,000
PMT = $0
FV = $75,000 × PVIFA factor at 10% for 21 years
= $75,000 × 8.6487
= $648,652.50
The following formula should be applied
= RATE(NPER;PMT;-PV;FV;TYPE)
The present value comes in negative
After applying the above formula, the rate of return is 6.06%
