Answer: The percentage gain is 45 percent
Step-by-step explanation: If 100 shares were bought at the rate of $15 per share, then the cost of buying all would be
100 x 15 and that equals 1500.
Then if all 100 shares were sold at the rate of $21.75 each, then the total amount realized upon sales would be
100 x 21.75 and that equals 2175
The profit realized from the sales of these shares therefore would be,
profit = selling price - cost price
profit = 2175 - 1500
profit = 675
The percentage gain (profit) would be a percentage of what was spent to buy the shares before eventually selling them, so our percentage gain would be calculated as follows;
% Gain = (Profit/Cost price) x 100/1
% Gain = (675/1500) x 100
% Gain = 45
The percentage gain therefore is 45 Percent.
