Suspense account

Hi John. Can you please let me know how to do this question please. I have spent a long time trying to to work this out.

Co’s draft financial statements for 20X5 showed a profit of $630,000. However, the trial balance did not agree, and a suspense account appeared in the company’s financial statements.
Subsequent checking revealed the following errors:
(1) The cost of an item of plant $48,000 had been entered in the cash book and in the plant
account as $4,800. Depreciation at the rate of 10% per year ($480) had been charged.
(2) Bank charges of $440 appeared in the bank statement in December 20X5 but had not been
entered in the company’s records.
(3) One of the directors paid $800 due to a supplier in K Co’s payables ledger by a personal
cheque. The bookkeeper recorded a debit in the supplier’s ledger account but did not
complete the double entry for the transaction (K Co does not maintain a payables ledger
control account).
(4) The payments side of the cash book had been understated by $10,000.
Note: in the exam, all questions will be independent, and not based on a common scenario.

What would the K Co’s profit be after the correction of the above errors?
A $634,760
B $624,760
C $624,440
D $625,240
