Answer:
The balance of retained earning is $130,000.
Explanation:
At the year end an adjusted trail balance is prepared, in which all the temporary accounts are closed and their balances are transferred to the permanent accounts. The adjusted trial balance must verify that debit and credit sides total is equal.
All the revenue and Expenses accounts are closed in Income summary account from where the net balance is transferred to the retained earning account.
Ending Balance of retained earning = Opening balance + Revenue - Expenses - Dividend
Ending Balance of retained earning = $80,000 + $125,000 - $60,000 - $15,000
Ending Balance of retained earning = $130,000
