  • 第1题:

    6 Ordan received a statement from one of its suppliers, Alta, showing a balance due of $3,980. The amount due

    according to the payables ledger account of Alta in Ordan’s records was only $230.

    Comparison of the statement and the ledger account revealed the following differences:

    1 A cheque sent by Ordan for $270 has not been allowed for in Alta’s statement.

    2 Alta has not allowed for goods returned by Ordan $180.

    3 Ordan made a contra entry, reducing the amount due to Alta by $3,200, for a balance due from Alta in Ordan’s

    receivables ledger. No such entry has been made in Alta’s records.

    What difference remains between the two companies’ records after adjusting for these items?

    A $460

    B $640

    C $6,500

    D $100


    正确答案:D
    3,980 – 270 – 180 – 3,200 = 330 : difference 100

  • 第13题:

    The following information is relevant for questions 9 and 10

    A company’s draft financial statements for 2005 showed a profit of $630,000. However, the trial balance did not agree,

    and a suspense account appeared in the company’s draft balance sheet.

    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 2005 but had not been entered in the

    company’s records.

    (3) One of the directors of the company paid $800 due to a supplier in the company’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. (The company does not maintain a payables ledger control account).

    (4) The payments side of the cash book had been understated by $10,000.

    9 Which of the above items would require an entry to the suspense account in correcting them?
