Final answer:
The amounts added or deducted in computing net income from the sale of the two buildings are recapture amounts and allowable capital losses.
Step-by-step explanation:
In computing net income from the sale of the two buildings, the amounts that would be added or deducted are as follows:
- For the first building, the recapture amount would be $12,000 (the undepreciated capital cost - the original cost) and the allowable capital loss would be $4,000 (the original cost - the selling price).
- For the second building, the recapture amount would be $10,000 (the undepreciated capital cost - the original cost) and the allowable capital loss would be $2,000 (the original cost - the selling price).
So, the correct answer is option b. recapture $10,000 and allowable capital loss $2,000.
