Cr realized gain on sale of short-term investment ($31,750-$30,500) $1,250
Step-by-step explanation:
The cash paid for the purchase of trading securities would be credited with $61,000 while the debit goes to short-term investment-trading
The 31st December year-end fair value adjusting entry is $5,000 ($66,000-$61,000) unrealized gain which would be debited to fair value adjustment-trading securities while the credit goes to unrealized gain-trading securities.
