Answer:
$370 (or 3.63%)
Step-by-step explanation:
An investor purchases 100 preferred stocks and pays 100 x $102 = $10,200. He then converts the 100 preferred stocks into 140 common stocks. Then the 140 common stocks are sold at 140 x $75.50 = $10,570.
The total profit = $10,570 - $10,200 = $370 or $370/$10,200 = 3.63%.
