3. Nominal ledger account in which,
- a record is kept of the total value of a number of similar individual items.
- mainly used for trade receivables and payables.
Receivables control account: in which records are kept of transactions
involving all receivables in total.
Payables control account: in which records are kept of transactions involving
all payables in total.
Control Account

4. Personal accounts
The amount owed by each credit customer is a balance on the receivables
ledger.
The amount owed by all the credit customer together is the balance on the
receivables control account.

5. Balance on the receivables control account = the sum of the individual
balances on the receivables ledger.
An organization have four trade receivable clients with having different
receivable amount:
Control Account and Personal Account
i. ABC Tk. 20
ii. XYZ Tk. 30
iii. DEF Tk. 25
iv. UVF Tk. 40
Total Tk.115
Personal Account
Receivable Control Account
Receivable Control Account Dr
Sales Cr

6. Operating control accounts
Contra: a person or business both a customer and a supplier, amounts
owed by and owed to the person may be ‘netted off’ by means of a contra.
Dr: Payables control a/c
Cr: Receivables control a/c
Irrecoverable debt: When a debt owed by a customer will never be paid,
the total amount is removed from receivables:
Dr: Irrecoverable debt expense
Cr: Receivables control a/c
Dishonored cheque: Customer’s cheque is paid into the business’s bank
but the customer’s bank refuses to honor payment:
Dr : Receivables control a/c
Cr : Cash

7. Operating control accounts
Accounting for wages :
The wages control account is used:
 To maintain the accuracy of payroll double entry
 To identify errors in payroll double entry.
When using the wages control account the objective is that at the end of
the process the account balance clears to zero: it is a clearing account.
This will affirm that the double entry has been made correctly, though
compensating errors could still exist.

25. Error in accounting
Transposition errors
When two digits in an amount are accidentally recorded
the wrong way round. (instead of 5353, 5335)
Errors of omission Failing to record a transaction at all, or making a debit or
credit entry, but not the corresponding double entry.
Errors of principal
Making a double entry in the belief that the transaction is
being entered in the correct accounts, but subsequently
finding out the accounting entry breaks the ‘rules’ of an
accounting principal or concept.
Errors of commission
A mistake is made in recording transactions in the
ledger accounts. (Telephone expenses recorded as
electricity expenses.
Compensating errors Errors which are, coincidentally, equal and opposite to
one another. (2822/2282, 8931/8391)

26. Journal:
Equal debit and credit entry to be passed.
Correcting Errors
A Co. wrongly reported Tk. 5,000 under Tax expenses instead of Electricity
expenses. Trial balance sum is Tk. 1,00,000 both side.
Debit: Electricity Tk.5,000
Credit: Tax Expenses Tk. 5,000

27. Correcting Errors
 A Co. receives an invoice for Tk. 500 from a supplier which was omitted
from the books entirely;
 Repairs Tk. 200 wrongly debited to Non- current assets;
 Sales reduced by Tk.250 as its presentation was not sure, in fact it was
drawing;
 Sales figure was added Tk. 3,250 instead of 3,520

28. Suspense Accounts
An account showing a balance equal to the difference in a trial balance
A suspense account is a temporary account which can be opened for the
following reasons-
 A trial balance is drawn up which does not balance
 The bookkeeper of a business knows where to post one side of a
transaction, but does not know where to post the other side.
Correcting Errors

29. A Company, on March 31, 2016, includes these selected accounts before adjusting entries
are prepared.
Debit Credit
Prepaid Insurance 3,600
Supplies 2,800
Equipment 25,000
Accumulated Depreciation—Equipment 5,000
Unearned Service Revenue 9,200
Correcting Errors
- An analysis shows the following:
- Insurance expires at the rate of 100 per month.
- Supplies on hand total 800.
- One-half of the unearned service revenue
was earned in March.
- The equipment depreciates 200 a month
Prepare the adjusting entries for the month of March

30. Correcting via ETB
Error may be corrected through Extended Trial Balance (ETB)

31. Last year question
(M/J 14 Q 4)
“A balanced trial balance does not always prove that the company has
recorded all transactions or that the ledger is correct” – Mention three
types of errors in support of this statement 6 Marks

32. Hywel plc's trial balance includes a total for all the receivables ledger accounts as
listed out at the year end. The receivables ledger is part of the double entry system.
The trial balance fails to agree and a suspense account is opened. The difference is
due to the following errors in Hywel plc's ledger accounts:
1. The balance on Markham plc's receivables ledger account is £9,890. This is
incorrectly recorded in the trial balance as £9,980
2. A discount allowed to Umberto of £33 was debited to his receivables ledger
account
3. The sales account is overcast by £110
Three journals are drafted to correct these errors. Together these journals should:
A credit the suspense account with £110
B debit the suspense account with £86
C credit the suspense account with £46
D debit the suspense account with £46
Question No. 1

33. This question is not asking for the balance on the suspense account, but for the
adjustment made to the suspense account by the correcting journal.
A single journal to correct all these errors would be:
CR Receivables (90 + 66) 156
DR Sales 110
DR Suspense (9,980 – 9,890) + (2 × 33) – 110 46
156 156
The debit entry in the suspense account is £46 (D)
Answer is D
Answer (Q. No. 1)

34. Dredge plc makes only statutory deductions from employees' pay, which are all paid to
HMRC when due. In March 20X6 Dredge plc paid £18,538 to its employees by bank
transfer. Gross pay for the month of £28,456 was debited to the salaries expense account,
but a debit balance of £3,983 remained on the salaries control account. This balance
represented:
A employer's NIC which should be debited to the salaries expense account
B employer's NIC which should be credited to the HMRC liability account
C total PAYE and NIC owed to HMRC for March which should be debited to the
salaries expense account
D PAYE and employees' NIC deducted from gross pay which should be debited to
the salaries expense account
Question No. 2

35. Employer’s NIC is an expense to the business in addition to gross pay, so it should be
debited to the salaries expense account from the control account (A). B is incorrect as it
suggests that the debit balance on the control account should be credited to the liability
account. Employees’ NIC and PAYE are not additional expenses, so the remaining debit
balance after gross pay has been charged cannot be these (C and D).
Answer is A
Answer (Q. No. 2)

36. Limbo plc maintains its petty cash records using an imprest system. The total petty cash float is
topped up monthly to £300. During the month of August the following expenses were paid from petty
cash:
Stationery 36 £
Tea and coffee 60 £
Stamps 120 £
In error, the purchase of stamps was recorded as £12 and as a result a cheque for £108 was written
to top up the petty cash float.
The error made will result in which of the following?
A . An imbalance in the trial balance of £108 and the petty cash balance being £108 less than it
should be
B. An understatement of expenses of £108 and the petty cash balance being £192 less than it
should be
C. An understatement of expenses of £108 and the petty cash balance being £108 less than it
should be
D. An imbalance in the trial balance of £192 and the petty cash balance being £192 less than it
should be
Question No. 3

37. The difference in the amount at which the purchase of stamps was recorded is £120 – £12 = £108.
As only £12 was recorded expenses have clearly been understated. Petty cash should have been
topped up with (£36 + £60 + £120) = £216, so the £108 top-up is £216 – £108 = £108 too little (C).
Answer is C
Answer (Q. No. 3)
