Complete the statement describing the standard double-entry accounting procedure required when a bad debt previously written off is subsequently recovered.

Aşağıdaki boşlukları doldurun

To properly record the recovery of a debt previously written off as irrecoverable, the customer's account is first reinstated by debiting the debtor's personal account and crediting the account. Next, the receipt of funds is recorded by debiting the cash or bank account and crediting the account.

Cevabı ve açıklamayı göster

Cevap

The first blank is 'Bad Debts Recovered' and the second blank is 'Debtor's' (or 'Trade Debtors').

When a debt previously written off is recovered, standard double-entry accounting mandates a two-stage entry: first, reinstate the debt by debiting the Debtor's Personal Account and crediting the Bad Debts Recovered Account; second, record payment by debiting Cash/Bank Account and crediting the Debtor's Personal Account.

Adım Adım Çözüm

1

Identify the entry needed to reinstate the debtor's personal account balance.

Debit the Debtor's Personal Account and credit the Bad Debts Recovered Account.

Reinstating the debtor's account ensures complete ledger history for credit rating and audit purposes before settling the account.

2

Record the receipt of cash/cheque from the debtor.

Debit Cash/Bank Account and credit the Debtor's Personal Account.

Receiving cash increases cash assets and clears the reinstated personal balance of the debtor.

Anahtar Kavram

Accounting entry for bad debts recovered requires reinstating the debtor's account first before crediting the receipt of cash to the debtor's account.

Tayo Traders had a trade debtors balance of $\text{₦}450,000$ before year-end adjustments for the financial year ended 31st December 2024. At the end of the year, additional unrecorded bad debts of $\text{₦}15,000$ were identified to be written off. During the same year, cash of $\text{₦}10,000$ was received from a customer whose debt of $\text{₦}10,000$ had been written off in 2022. What is the net trade debtors balance to be shown in the Statement of Financial Position as at 31st December 2024?

Cevap

The net trade debtors balance to be shown in the Statement of Financial Position at 31st December 2024 is

\text{₦}435,000

.

To calculate the net trade debtors figure for the Statement of Financial Position, only additional bad debts written off at year-end (

\text{₦}15,000

) are deducted from the unadjusted trade debtors balance of

\text{₦}450,000

, resulting in

\text{₦}435,000

. Bad debts recovered (

\text{₦}10,000

) are recognized as revenue in the Income Statement and received in cash, having no effect on closing trade debtors.

Adım Adım Çözüm

1

Determine the unadjusted trade debtors balance

Unadjusted Trade Debtors =

\text{₦}450,000

This represents the recorded receivables prior to writing off year-end unrecorded bad debts.

2

Subtract additional bad debts written off at year-end

Adjusted Trade Debtors =

\text{₦}450,000 - \text{₦}15,000 = \text{₦}435,000

Bad debts written off represent irrecoverable amounts and must be deducted directly from trade debtors.

3

Evaluate the treatment of bad debts recovered

Effect on Trade Debtors =

\text{₦}0

Bad debts recovered during the year are recorded by debiting Cash/Bank and crediting Bad Debts Recovered (an income account). Because the original personal account of the debtor was already cleared when written off in a previous period, recovery does not alter the closing trade debtors balance.

A trading enterprise recently implemented a modern computerized accounting system. Management assumed that because the newly installed accounting application software and server hardware feature automated processing algorithms, the system would automatically eliminate internal accounting errors and fraud without requiring written operational guidelines, internal approval workflows, or staff oversight. Which fundamental principle concerning the components of a computerized accounting system did management fail to appreciate?

Automated system software merges hardware and database layers, thereby rendering human oversight and user management redundant.

Hardware and software components cannot replace procedural internal controls and personnel oversight in maintaining system data integrity.

Accounting application software acts as system software that converts periodic batch processing into continuous real-time processing without user input.

Computerized accounting components automatically unify routine transaction recording with high-level financial interpretation without human intervention.

Cevap: Hardware and software components cannot replace procedural internal controls and personnel oversight in maintaining system data integrity.

Cevap

Hardware and software components cannot replace procedural internal controls and personnel oversight in maintaining system data integrity.

A Computerized Accounting System (CAS) relies on five essential components: Hardware, Software, Data, Procedures, and Peopleware. Management's mistake was assuming that acquiring advanced hardware and application software removes the necessity of internal control procedures and administrative oversight. Technology automates processing speed and accuracy but cannot enforce organizational accountability or prevent fraudulent data input without rigorous procedural controls and human monitoring.

Adım Adım Çözüm

1

Identify the five core components of a Computerized Accounting System (CAS).

A complete CAS consists of Hardware, Software, Data/Database, Procedures (internal controls and operational rules), and Peopleware (users and administrators).

Evaluating system integrity requires viewing all five components as interdependent elements.

2

Analyze management's erroneous assumption in the scenario.

Management relied solely on technology (hardware and application software) while neglecting procedural controls and human oversight (peopleware).

Software executes instructions accurately, but without authorization procedures and user access controls, fraudulent or erroneous data can still enter the system.

3

Determine the correct accounting principle governing system controls.

Computerization does not eliminate internal control risks; hardware and software must be paired with well-defined procedures and diligent peopleware oversight.

Cevabı ve açıklamayı göster

Cevap: Partner's Current Account

Cevap

Partner's Current Account

Under the fixed capital account system, the partner's capital account maintains a constant balance containing only initial capital, permanent additions, or permanent capital withdrawals. All recurring operational allocations such as profit shares, partner salaries, interest on capital, and drawings are credited or debited to the partner's current account.

Adım Adım Çözüm

1

Identify the accounting method specified in the prompt

The firm uses the fixed capital account method.

Partnership accounting distinguishes between fixed and fluctuating capital methods.

2

Apply the rule of the fixed capital account method

The Capital Account balance is kept fixed, while all annual appropriations (profit share, salaries, drawings, interest) are posted to the Current Account.

This maintains the initial capital structure distinct from accumulated profits and appropriations.

3

Determine the crediting account for share of profit

The share of profit increases the partner's equity, so it is credited to the Partner's Current Account.

Crediting the current account reflects the allocation of profits available to the partner without altering original capital.

accommodating (or flexible / yielding / compliant / cooperative)

The sentence uses the contrastive conjunction 'whereas' to contrast the union leader's refusal to compromise with the management's behavior. 'Intransigent' means unwilling or refusing to change one's views or agree about something. Therefore, an antonym such as 'accommodating', 'flexible', or 'yielding' correctly completes the sentence.

Adım Adım Çözüm

1

The word 'intransigent' refers to someone who is stubborn, uncompromising, or refusing to change their views.

Understanding the precise contextual definition of the target word is necessary before determining its opposite.

2

Identify the contrasting relationship established in the sentence structure.

The conjunction 'whereas' sets up a direct opposition between the stance of the union leader and that of the management.

Since the union leader was uncompromising ('intransigent'), management's contrasting behavior requires a word meaning willing to compromise or adapt.

3

Select the appropriate antonym that completes the blank grammatically and semantically.

Words such as 'accommodating', 'flexible', 'yielding', or 'compliant' serve as accurate contextual antonyms for 'intransigent'.

The text explains that municipal authorities view spontaneous social networks 'merely as chaotic rather than vital structures.'

Contextual clues reveal the attitude of the authorities toward these networks.

1 - 2\sin x \cos x = \frac{1}{5}

, which simplifies to

\sin x \cos x = \frac{2}{5}

. Expressing

\tan x + \cot x

in terms of sine and cosine gives

\frac{\sin^2 x + \cos^2 x}{\sin x \cos x} = \frac{1}{\sin x \cos x}

. Substituting

\frac{2}{5}

gives

\frac{1}{2/5} = \frac{5}{2}

.

Adım Adım Çözüm

1

Square both sides of the given equation

\sin x - \cos x = \frac{1}{\sqrt{5}}

(\sin x - \cos x)^2 = \left(\frac{1}{\sqrt{5}}\right)^2 \implies \sin^2 x - 2\sin x \cos x + \cos^2 x = \frac{1}{5}

Squaring enables the use of the Pythagorean trigonometric identity.

2

Apply the fundamental identity

\sin^2 x + \cos^2 x = 1

to isolate

\sin x \cos x

1 - 2\sin x \cos x = \frac{1}{5} \implies 2\sin x \cos x = 1 - \frac{1}{5} = \frac{4}{5} \implies \sin x \cos x = \frac{2}{5}

This determines the value of the product of sine and cosine.

3

Rewrite

\tan x + \cot x

using quotient identities

\tan x + \cot x = \frac{\sin x}{\cos x} + \frac{\cos x}{\sin x} = \frac{\sin^2 x + \cos^2 x}{\sin x \cos x} = \frac{1}{\sin x \cos x}

Expressing tangent and cotangent with a common denominator simplifies the expression into a reciprocal.

4

Substitute

\sin x \cos x = \frac{2}{5}

into the simplified expression

\tan x + \cot x = \frac{1}{2/5} = \frac{5}{2}

Inverting the fraction gives the final numerical answer.

Read the passage excerpt below carefully:

"In his treatise on cognitive architecture, the philosopher noted that empirical inquiries often fail not because the instruments are defective, but because investigators attempt to sound the depths of human consciousness using metrics calibrated only for superficial behavioral observations."

In the passage above, what is the contextual meaning of the word sound?

Cevabı ve açıklamayı göster

Cevap: fathom or measure the depth of

Cevap

In the given excerpt, the word 'sound' contextually means to fathom or measure the depth of.

The option stating 'fathom or measure the depth of' is correct because 'sound' is used contextually as a verb derived from nautical measurement (plumbing depths). In philosophical and literary contexts, 'to sound the depths' is an established idiom meaning to investigate or penetrate deep, complex ideas.

Adım Adım Çözüm

1

Analyze the grammatical function of the target word in context.

The word 'sound' follows the infinitive marker 'to' ('attempt to sound the depths...') and takes 'the depths' as its direct object, functioning as a transitive verb.

Identifying the part of speech eliminates meanings associated with adjectives or nouns.

2

Examine the surrounding contextual clues and imagery.

The phrase 'sound the depths... using metrics calibrated only for superficial... observations' uses nautical measurement metaphors where depth and calibration are contrasted with surface observations.

Contextual clues reveal that the author is contrasting deep measurement with superficial observation.

3

Select the synonym that correctly matches the metaphor and syntax when substituted.

Substituting 'fathom' or 'measure the depth of' yields: 'attempt to fathom the depths of human consciousness', which preserves both exact meaning and sentence structure.

Cevap: 28

Cevap

The value of

y

when

is 28.

By representing partial variation as

y = c + kx

, substituting the given conditions gives two simultaneous linear equations:

10 = c + 2k

and

19 = c + 5k

. Subtracting the first equation from the second yields

3k = 9

, so

k = 3

. Substituting

k = 3

back into the first equation yields

c = 4

. The general equation is

y = 4 + 3x

. Evaluating at

x = 8

gives

y = 4 + 3(8) = 28

.

Adım Adım Çözüm

1

Set up the partial variation equation

y = c + kx

, where

c

Partial variation consists of a fixed term plus a variable term.

2

Substitute given values to form simultaneous equations

Equation 1:

10 = c + 2k

Equation 2:

19 = c + 5k

Two pairs of

values are provided to solve for the two unknown constants

c

and

(1 + 5) - 3 = 3

for the units place and

3 - 2 = 1

for the fives place.

Adım Adım Çözüm

1

Set up column subtraction for

41_5 - 23_5

in base 5.

In the units position, we evaluate

1 - 3

.

Since 1 is smaller than 3, a borrow operation from the fives column is required.

2

Borrow 1 from the fives column (reducing 4 to 3) and add the base value 5 to the units digit 1.

Units column value becomes

1 + 5 = 6

. Fives column value becomes 3.

When borrowing in base

n

, the borrowed amount is equal to

n

, which is 5 for base 5.

3

Subtract digits in each column.

Units column:

6 - 3 = 3

. Fives column:

3 - 2 = 1

. The result is

13_5

.

Completing the column subtraction yields the final digits in base 5.

Given that $P$ varies directly as the square of $r$ , and $P = 48$ when $r = 4$ , calculate the value of $P$ when $r = 6$ .

Cevabı ve açıklamayı göster

Cevap: 108

Cevap

The value of

P

when

r = 6

is

108

.

Since

P

varies directly as

r^2

, the relationship is expressed as

P = k r^2

. Substituting the given values

P = 48

and

r = 4

yields

48 = 16k

, so

k = 3

. Substituting

k = 3

and

r = 6

into the equation gives

P = 3 \times 6^2 = 3 \times 36 = 108

.

Adım Adım Çözüm

1

Set up the variation equation using constant of variation

k

P = k r^2

Direct variation with the square of a variable means

P

is directly proportional to

r^2

.

2

Substitute the initial values

P = 48

and

r = 4

to determine

k

48 = k \times 4^2 \implies 48 = 16k \implies k = 3

Finding the variation constant

k

allows us to establish a specific relationship between

P

and

r

.

3

Calculate

P

for

r = 6

using the specific equation

P = 3 r^2

P = 3 \times 6^2 = 3 \times 36 = 108

Evaluating the formula with the new input

r = 6

yields the required value of

P

.

intransigent (or obdurate / unyielding)

The word 'recalcitrant' means stubbornly resistant to authority, control, or persuasion. In the context of a labor dispute where a leader refuses to compromise despite mediation, 'intransigent' (or 'obdurate') accurately expresses this uncompromising stance.

Adım Adım Çözüm

1

Analyze the meaning of the target word 'recalcitrant' within the sentence context.

The target word describes an individual who is stubbornly defiant of authority or resistant to compromise.

The surrounding phrase 'refusal to concede any demands' despite repeated mediation indicates an obstinate and inflexible posture.

2

Determine the word nearest in meaning that maintains both semantic precision and formal register.

'Intransigent' (or 'obdurate') serves as the exact contextual synonym.

Both 'recalcitrant' and 'intransigent' signify an unyielding refusal to change one's stance or come to an agreement.
