Trial Balance Errors (45 Questions)
QUESTION 1: What type of error occurs when a $500 sale is recorded as $5,000?
Answer: Slide error
Rationale: A slide error involves shifting the decimal point, changing the magnitude of the
amount (e.g., $500 to $5,000) ().
QUESTION 2: What is the likely cause of a trial balance where total debits do not equal total
credits and the difference is divisible by 9?
Answer: Transposition error
Rationale: A transposition error (e.g., $74 recorded as $47) results in a difference divisible by 9
().
QUESTION 3 (Scenario-Based): A trial balance shows Accounts Receivable with a credit
balance of $2,000. What type of error is this?
Answer: Incorrect balance type
Rationale: Accounts Receivable normally has a debit balance; a credit balance indicates an
error, likely from misposting or misclassification ().
QUESTION 4: How can you detect an error where a debit is recorded as a credit in a trial
balance?
Answer: Difference between debits and credits is divisible by 2
Rationale: Reversing a debit and credit (e.g., debit $100 as credit) doubles the error, making the
difference divisible by 2 ().
,QUESTION 5 (Select All That Apply): Which errors can cause a trial balance to be out of
balance? Select all that apply: Transposition, Omission, Classification, Slide, Incorrect
accounting principle.
Answer: Transposition, Omission, Slide
Rationale: Transposition, omission, and slide errors affect trial balance totals. Classification and
incorrect principles may not cause imbalance ().
QUESTION 6: What type of error occurs when a purchase is not recorded at all?
Answer: Omission error
Rationale: An omission error occurs when a transaction is completely unrecorded ().
QUESTION 7 (Scenario-Based): A trial balance lists Accumulated Depreciation with a debit
balance of $5,000. What is the likely error?
Answer: Incorrect balance type
Rationale: Accumulated Depreciation should have a credit balance; a debit balance suggests a
posting error ().
QUESTION 8: What type of error involves debiting an expense to the wrong account, such as
Insurance Expense instead of Rent Expense?
Answer: Classification error
Rationale: A classification error occurs when a transaction is recorded in the wrong account ().
QUESTION 9 (Select All That Apply): Which methods help identify trial balance errors?
Select all that apply: Comparing with prior year, Reviewing account balances, Bank
reconciliation, Using incorrect estimates, Checking journal entries.
Answer: Comparing with prior year, Reviewing account balances, Checking journal entries
Rationale: These methods detect anomalies. Bank reconciliation is separate, and incorrect
estimates don’t directly identify errors ().
QUESTION 10 (Scenario-Based): A trial balance is out of balance by $180, divisible by 9.
What is the likely error?
Answer: Transposition error
Rationale: A difference divisible by 9 suggests a transposition error, such as $810 recorded as
$180 ().
, QUESTION 11: What type of error occurs when depreciation is calculated using a 5-year life
instead of a 3-year life?
Answer: Improper accounting estimate
Rationale: Using an incorrect useful life is an estimation error ().
QUESTION 12: How can you identify a slide error in a trial balance?
Answer: Check for decimal point shifts in recorded amounts
Rationale: Slide errors involve incorrect decimal placement, detectable by reviewing amounts ().
QUESTION 13 (Scenario-Based): A trial balance shows a $900 difference divisible by 2. What
is a possible cause?
Answer: Debit recorded as credit
Rationale: A debit recorded as a credit (or vice versa) causes a difference divisible by 2 ().
QUESTION 14 (Select All That Apply): Which errors do not cause a trial balance imbalance?
Select all that apply: Transposition, Classification, Omission, Slide, Posting to wrong account.
Answer: Classification, Posting to wrong account
Rationale: Classification and posting errors affect account types but not total debits/credits.
Transposition, omission, and slide errors cause imbalances ().
QUESTION 15: What type of error occurs when a $1,200 payment is recorded as $120?
Answer: Slide error
Rationale: A slide error involves shifting the decimal point, altering the amount’s magnitude ().
QUESTION 16 (Scenario-Based): A trial balance is out of balance by $270, divisible by 9.
What is the likely error?
Answer: Transposition error
Rationale: A difference divisible by 9 indicates a transposition error, such as $720 recorded as
$270 ().
QUESTION 17 (Select All That Apply): Which errors affect trial balance totals? Select all that
apply: Incorrect account classification, Omission of a transaction, Posting to wrong account,
Debit as credit, Double posting.
Answer: Omission of a transaction, Debit as credit, Double posting
