Final answer:
To find the gain or loss from buying and selling shares, we need to know the purchase and selling prices.
Step-by-step explanation:
To find the amount of money gained or lost from buying and selling shares, we need to know the purchase and selling prices of the shares. Unfortunately, the question does not provide this information. Without the purchase and selling prices, we cannot determine the gain or loss. If you can provide the purchase and selling prices, I will be able to calculate the gain or loss for you.
