Answer:
a. $20,000
b. -$2,950
c. -29.50%
Explanation:
The computation is shown below:
a. Gross Profit is
= Sale value of Property - Invested amount - Mortgage amount
= $120,000 - $10,000 - $90,000
= $20,000
b. Net Profit
= Gross profit - number of years × mortgage amount × rate of interest
= $20,000 - 3 × $90,000 × 8.5%
= -$2,950
And,
c) Rate of return is
= Net profit ÷ invested amount
= -$2,950 ÷ $10,000
= -29.50%
