Answer:
The amount and character of Alpha's gain are $20,000 and a positive value.
Step-by-step explanation:
Given;
For Alpha,
Cost of machinery = $50,000
Depreciation expense claimed on machinery = $30,000 (accumulated)
Netbook value of machinery = $50,000 - $30,000
= $20,000
Income from disposal of machinery to Beta = $40,000
Gain/(loss) on disposal of machinery = $40,000 - $20,000
= $20,000
The amount and character of Alpha's gain are $20,000 and a positive value.
