Answer:
There is a loss on disposal of $10000 and option C is the correct answer.
Explanation:
The units of production method charges depreciation based on the activity level that the asset is used for during a period
The depreciation rate under this method is,
Depreciation per hour = (240000 - 40000) / 10000 = $20 per hour
The depreciation for the Year 2015 and 2016 under the units of production method is,
2015 = 20 * 2400 = $48000
2016 = 20 * 2100 = $42000
The accumulated depreciation at the end of 2016 is = 48000 + 42000 = $90000
The carrying value at the end of 2016 is = 240000 - 90000 = $150000
The gain/loss on disposal = 140000 - 150000 = - $10000 or a loss of $10000
