Answer:
Option B. I made a profit of $75.
Explanation:
If I bought 20 shares of the stock at the rate of $31.5 and sold it at $35.25 then we have to calculate the net output.
With the purchase of 20 shares total amount invested = 20×31.5 = $630
and by selling these shares at $35.25 I got the money = 20×35.25 = $705
here we see the selling amount is higher than costing amount therefore i made a profit of $705 - $630 = $75.
Therefore option B is the answer.
