Answer:
c. $25,000
Explanation:
We recognize impairment loss when the Carrying Amount of an Asset is greater than its Recoverable Amount.
Recoverable Amount of an Asset is the Higher of Asset Fair Value and Value in use. The future cash shows represent value in use and these need to be discounted. Since they are not, Recoverable Amount = $275,000
Carrying Amount of an Asset is the Cost of the Asset less all depreciation charges to date of the impairment test, Carrying Amount = $300,000
Therefore, Impairment loss = $25,000 ($300,000 - $275,000)
