Answer:
Comprehensive income as of 31st December is $320,000.
Step-by-step explanation:
Comprehensive income = Operating profits + Unrelated profits.
The value of unrelated profit is the profit realised as a result of the disposal of debt securities, which does not form part of the core operation of the company which is therefore unrelated.
Comprehensive income is therefore=(Sales revenue - Cost of goods sold + Operating expenses) + Net of tax.
Comprehensive profit =($800,000 - $600,000 + $90,000) + $30,00
= $320,000.
Comprehensive income as of 31st December, is therefore $320,000.
