Answer:
The correct answer is a loss of $36,000.
Explanation:
Gain or loss on disposal of an asset is calculated by deducting the net book value (NBV) of the asset from the sales proceeds. The NBV is historical cost minus accumulated depreciation.
Therefore, the NBV of the tractor is $135,000 - $69,000 = $66,000
Gain or loss = $30,000 - $66,000
Loss of $36,000, since the sales proceed is less than the NBV.
