Answer:
Part 1: Book Value of Machine at the end Year 2 is $13,130
Part 2: Depreciation charge per year after revision in estimates is $3,710
Explanation:
PART 1
Depreciation charge per year = (Cost – Salvage Value) ÷ Useful Life
Depreciation charge per year = ($23,860 – $2,400) ÷ 4 Years
Depreciation charge per year = $5,365 per Year
Cost of Machine $23,860
Depreciation Charge of Year 1 $(5,365)
Book Value at the end of year 1 $18,495
Depreciation charge of year 2 $(5,365)
Book value at the end of year 2 $13,130
PART 2
Revised Deprecation Charge per year = (Cost – Revised Salvage Value – Accumulated Depreciation) ÷ Revised Remaining Useful Life
Revised Deprecation Charge per year = ($23,860 – $2,000 – $10,730) ÷ 3 Years
Revised Deprecation Charge per year = $3,710 per Year
Book Value before revision in estimate $13,130
After Revision in estimates:
Depreciation charge of year 1 $(3,710)
Book Value at the end of Year 1 $9,420
Depreciation charge of year 2 $(3,710)
Book Value at the end of Year 2 $5,710
Depreciation charge of year 3 $(3,710)
