To write up the asset account (Motor Vehicles) from 1996 to 31st December 1998, we need to record the acquisitions and disposals of vehicles during this period. The asset account will show the original cost of each vehicle, any depreciation expenses, and the net book value at the end of each year.
Here is the asset account for Motor Vehicles from 1996 to 31st December 1998:
Year 1996:
Vehicle #356 - Acquisition: $2,100,000
Total: $2,100,000
Year 1997:
Vehicle #258 - Acquisition: $3,600,000
Vehicle #124 - Acquisition: $2,400,000
Vehicle #347 - Acquisition: $5,400,000
Total: $11,400,000
Year 1998:
Vehicle #546 - Acquisition: $2,500,000
Vehicle #258 - Disposal: $2,000,000
Vehicle #356 - Disposal: $1,500,000
Total acquisitions: $2,500,000
Total disposals: $3,500,000
Net Book Value as of 31st December 1998: $9,100,000 ($11,400,000 - $3,500,000)
Next, let's write up the depreciation account from 1996 to 31st December 1998. Since the straight-line method is used and a full year's depreciation is made in the year of purchase, we'll calculate the depreciation expense for each year based on the original cost of the vehicles.
Depreciation Account from 1996 to 31st December 1998:
Year 1996:
Vehicle #356 - Depreciation Expense: $420,000 ([$2,100,000 / 5] x 1 year)
Total: $420,000
Year 1997:
Vehicle #258 - Depreciation Expense: $720,000 ([$3,600,000 / 5] x 1 year)
Vehicle #124 - Depreciation Expense: $480,000 ([$2,400,000 / 5] x 1 year)
Vehicle #347 - Depreciation Expense: $900,000 ([$5,400,000 / 5] x 1 year)
Total: $2,100,000
Year 1998:
No depreciation since there are no acquisitions
Finally, let's write up the disposal account for 1998. Since there is no depreciation in the year of disposal, the disposal account will only record the proceeds from the sale of the vehicles.
Disposal Account for 1998:
Vehicle #258 - Proceeds from Sale: $2,000,000
Vehicle #356 - Proceeds from Sale: $1,500,000
Total: $3,500,000
Please note that the asset account, depreciation account, and disposal account should be presented in the format required by your instructor or the accounting standards in your region. This is a simplified example, but it should give you an understanding of how to write up these accounts based on the given information.
