Answer and Explanation:
The computation is shown below:
Cost of Assets $500,000
Less: Accumulated Depreciation -$200,000
Net book value as on 31st Dec 2017 $300,000
Less: Amount realized after sale of an asset -$225,000
Loss from sale of asset $75,000
As the book value is $300,000 and the sale value of an asset is $225,000
so there is a loss of $75,000 from this given transaction
