You bought 100 shares of stock at $15 per share. You sold your 100 shares at $21.75 per share. Calculate your percentage of gain.

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.
