Answer:
Depreciation per annum = Cost - Salvage value/N
$4,000 = $54,000 - $6,000/N
4,000N = 48,000
N = 12 years
The estimated useful year of the asset = 12 years
The accumulated depreciation is $16,000
This implies that depreciation of $4,000 has been charged for 4 years
Thus, the remaining useful life of the asset is 12 years - 4 years = 8 years
Step-by-step explanation:
In this scenario, there is need to calculate the estimated useful life of the asset based on straight line depreciation formula. In this case, the estimated useful life becomes the subject of the formula.
We also need to determine the number of years depreciation has been charged. Since the accumulated depreciation is $16,000, it means depreciation has been charged for 4 years based on annual depreciation charge of $4,000. The remaining useful life is the difference between the estimated useful life(12 years) and number of years depreciation has been charged(4 years).
