The closing capital can be calculated by adding the opening capital and the capital introduced, and then subtracting the profit for the year and the cash drawings.
Starting with the opening capital of #1,500, we add the capital introduced of ₦500, which gives us #2,000.
Next, we add the profit for the year of ₦800, which gives us #2,800.
Finally, we subtract the cash drawings of ₦250, which gives us a closing capital of #2,550.
Therefore, the closing capital is #2,550.
