Answer:
The correct answer is A that is $31,000.
Explanation:
The aggregate amount of stockholders' equity is computed as:
Stockholders' equity = Common Stock + Additional paid in capital in excess of par value + Retained Earnings - Treasury Stock
where
Common Stock = $12,000
Additional paid in capital in excess of par value = $11,000
Retained Earnings = $12,000
Treasury Stock = $4,000
Putting the values in the above formula:
= $12,000 + $11,000 + $12,000 - $4,000
= $31,000
Therefore, the amount of Stockholders' equity is $31,000.
