Answer:
Unrealized gain $2,500
Explanation:
The computation of the unrealized loss or gain is shown below:
Gain = Fair value - book value
Loss is opposite of gain i.e
Loss = Book value - fair value
where,
Fair value is $80,000
And, the book value is
= Cost of trading securities portfolio - credit balance
= $100,000 - $22,500
= $77,500
So, the unrealized gain is
= $80,000 - $77,500
= $2,500
This is the answer and the given options are wrong
