At the end of an accounting period, a trading enterprise holds two categories of unsold inventory with the following details:

- Product Alpha: Cost price of $\text{N}28,000$ , estimated selling price of $\text{N}32,000$ , and estimated selling expenses of $\text{N}5,000$ .
- Product Beta: Cost price of $\text{N}42,000$ , estimated selling price of $\text{N}50,000$ , and estimated selling expenses of $\text{N}3,000$ .

In accordance with the prudence concept, what is the total valuation of closing stock to be credited to the Trading Account in Naira?

Cevabı ve açıklamayı göster

Cevap: 69000

Cevap

69,000 Naira

Closing inventory must be valued at the lower of cost and net realizable value for each item. For Product Alpha, the NRV of

\text{N}27,000

(

32,000 - 5,000

) is lower than its cost of

\text{N}28,000

. For Product Beta, the cost of

\text{N}42,000

is lower than its NRV of

\text{N}47,000

(

50,000 - 3,000

). Summing these lower values (

27,000 + 42,000

) gives a total closing stock valuation of 69,000 Naira.

Adım Adım Çözüm

1

Calculate Net Realizable Value (NRV) for Product Alpha and Product Beta.

Product Alpha NRV =

\text{N}27,000

; Product Beta NRV =

\text{N}47,000

.

Net Realizable Value is determined by subtracting estimated completion and selling costs from the estimated selling price.

2

Compare cost and NRV for each category to select the lower value.

Product Alpha valuation =

\text{N}27,000

; Product Beta valuation =

\text{N}42,000

.

The prudence concept mandates that closing stock is valued at the lower of cost and net realizable value on an item-by-item basis to avoid overstating assets and profit.

3

Sum the selected valuation figures for all inventory categories.

Total Closing Stock =

27,000 + 42,000 = \text{N}69,000

.

Total inventory valuation is the combined value of all individual stock categories.

A topographical map with a scale of $1 : 100,000$ depicts a reservoir that covers an area of $16\text{ cm}^2$ on the map. If the map is reduced to a new scale of $1 : 250,000$ , what is the area of the reservoir on the new reduced map in square centimeters ( $\text{cm}^2$ )?

Cevabı ve açıklamayı göster

Cevap: 2.56

Cevap

The area of the reservoir on the new map is

2.56\text{ cm}^2

.

To calculate the new map area after reduction, first find the linear scale factor

k = \frac{100,000}{250,000} = 0.4

. Because area changes in proportion to the square of linear dimensions, the area scale factor is

(0.4)^2 = 0.16

. Multiplying the original map area (

16\text{ cm}^2

) by

0.16

gives the correct new area of

2.56\text{ cm}^2

.

Adım Adım Çözüm

1

Determine the linear scale factor (

k

)

k = \frac{\text{Original Scale Denominator}}{\text{New Scale Denominator}} = \frac{100,000}{250,000} = 0.4

Map reduction changes linear dimensions proportionally to the ratio of original scale denominator to new scale denominator.

2

Calculate the area scale factor (

k^2

)

k^2 = (0.4)^2 = 0.16

Map area varies with the square of the linear scale factor.

3

Compute the new map area

\text{New Area} = \text{Original Area} \times k^2 = 16\text{ cm}^2 \times 0.16 = 2.56\text{ cm}^2

Applying the area scale factor to the original map area gives the reduced surface area on the new map.

Cevap: 52000

Cevap

52000

According to the accrual concept of accounting, subscription income credited to the Income and Expenditure Account reflects income earned for the current financial period regardless of cash receipt timing: Subscription Income = Cash Received (N50,000) + Opening Advance (N4,000) + Closing Arrears (N6,000) - Opening Arrears (N5,000) - Closing Advance (N3,000) = N52,000.

Start with cash subscriptions received during the period

N50,000

This is the actual cash collected and recorded in the Receipts and Payments account.

2

Add subscriptions received in advance at the beginning of the period and accrued subscriptions at the end of the period

N50,000 + N4,000 + N6,000 = N60,000

Advance subscriptions from the start belong to the current year, and accrued subscriptions at year-end represent current year income earned but not yet collected.

3

Deduct subscriptions accrued at the beginning of the period and subscriptions received in advance at the end of the period

N60,000 - N5,000 - N3,000 = N52,000

Opening accrued subscriptions were earned in the previous period, and closing advance subscriptions belong to the subsequent accounting period.

- Total Rent and Rates: ₦60,000 (apportioned based on floor space: Department X occupies $1,200\text{ m}^2$ and Department Y occupies $800\text{ m}^2$ )
- Total Staff Salaries: ₦40,000 (apportioned based on staff headcount: Department X has 6 employees and Department Y has 4 employees)

What is the Net Profit of Department X in Naira (₦)?

Cevabı ve açıklamayı göster

Cevap: 65000

Cevap

The Net Profit of Department X is ₦65,000.

To find the Net Profit of Department X, calculate the apportioned share of shared expenses and add direct expenses. Rent apportioned to Department X based on floor space is

\frac{1,200}{2,000} \times ₦60,000 = ₦36,000

. Salaries apportioned based on headcount are

\frac{6}{10} \times ₦40,000 = ₦24,000

. Adding direct administrative expenses of

₦25,000

yields total expenses of

₦36,000 + ₦24,000 + ₦25,000 = ₦85,000

. Subtracting total expenses from the Gross Profit (

₦150,000 - ₦85,000

) gives a Net Profit of

₦65,000

.

Koko Plc offered $100,000$ ordinary shares of $\text{₦}1.00$ each at a premium of $20\%$ . Payment terms per share were as follows:
- On application: $\text{₦}0.30$
- On allotment: $\text{₦}0.40$ (including the full premium)
- On first and final call: $\text{₦}0.50$

Applications were received for $120,000$ shares. The company allotted shares on a pro-rata basis to all applicants, with surplus application money applied towards the amount due on allotment. If all monies due on allotment were paid, what is the net cash amount (in Naira) received on allotment?

Cevap: 34000

Cevap

The net cash amount received on allotment is 34,000 Naira.

The gross amount due on allotment for 100,000 shares at ₦0.40 per share (inclusive of premium) is ₦40,000. Because 120,000 shares were applied for at ₦0.30 per share, the company received ₦36,000 initially. Since only ₦30,000 was needed for the 100,000 allotted shares, a surplus of ₦6,000 was transferred to the allotment account. Consequently, the net cash collected on allotment is ₦40,000 - ₦6,000 = ₦34,000.

On a topographical map drawn to a scale of $1:100,000$ , a hill summit is marked with a spot height of $520\text{ m}$ . The terrain features uniform contour intervals of $20\text{ m}$ . Point $X$ is located on the fifth contour line directly below the summit. Point $Y$ is situated at a lower elevation such that the vertical difference in height between Point $X$ and Point $Y$ is $240\text{ m}$ . If the straight-line distance measured between Point $X$ and Point $Y$ on the map is $6\text{ cm}$ , calculate the average gradient between Point $X$ and Point $Y$ expressed in the ratio $1 : n$ . What is the value of $n$ ?

Cevabı ve açıklamayı göster

Cevap: 25

Cevap

The value of

n

is 25, corresponding to an average gradient of

1 : 25

(or 1 in 25).

To find the denominator

n

of the gradient ratio

1:n

, the vertical interval (VI =

240\text{ m}

) is compared to the horizontal equivalent (HE =

6,000\text{ m}

). Dividing

6,000\text{ m}

by

240\text{ m}

yields

25

, meaning the slope rises 1 meter vertically for every 25 meters horizontally.

Adım Adım Çözüm

1

Determine the elevation of Point X from the contour interval and spot height.

Elevation of Point X =

520\text{ m} - (5 \times 20\text{ m}) = 420\text{ m}

.

Point X lies on the fifth contour line below the

520\text{ m}

summit with a

20\text{ m}

interval.

2

Identify the Vertical Interval (VI) between Point X and Point Y.

\text{VI} = 240\text{ m}

.

The vertical elevation difference is directly specified in the problem statement.

3

Convert map distance to actual ground horizontal distance (Horizontal Equivalent, HE) using the map scale.

\text{HE} = 6\text{ cm} \times 100,000 = 600,000\text{ cm} = 6,000\text{ m}

.

Unit conversions must align VI and HE in meters before computing the ratio.

4

Express the gradient as a ratio

1 : n

by dividing HE by VI.

n = \frac{\text{HE}}{\text{VI}} = \frac{6,000\text{ m}}{240\text{ m}} = 25

.

Gradient ratio is defined as

\frac{\text{Vertical Interval}}{\text{Horizontal Equivalent}} = \frac{1}{n}

- $N_2$ (2nd-order streams) = $10$
- $N_3$ (3rd-order streams) = $4$

Cevap: 3.5

Cevap

The mean bifurcation ratio (

R_b

) of the drainage basin is 3.5.

The mean bifurcation ratio (

R_b

) is obtained by computing the ratio of stream segments between successive orders:

N_1/N_2 = 4.0

,

N_2/N_3 = 2.5

, and

N_3/N_4 = 4.0

. Averaging these three values gives

(4.0 + 2.5 + 4.0) / 3 = 3.5

.

Adım Adım Çözüm

1

Calculate the individual bifurcation ratios (

R_b

) between consecutive stream orders using the formula

R_b = \frac{N_u}{N_{u+1}}

.

R_{b(1-2)} = \frac{40}{10} = 4.0

,

R_{b(2-3)} = \frac{10}{4} = 2.5

, and

R_{b(3-4)} = \frac{4}{1} = 4.0

.

Bifurcation ratio measures the ratio of the number of stream segments of a given order to the number of segments of the next higher order.

2

Sum the calculated individual bifurcation ratios.

Sum

= 4.0 + 2.5 + 4.0 = 10.5

.

To find the average across all order transitions, the sum of all calculated ratios must first be determined.

3

Divide the total sum by the number of order transitions (

k = 3

).

Mean

R_b = \frac{10.5}{3} = 3.5

.

There are 3 transitions between the 4 stream orders, so dividing the sum by 3 gives the arithmetic mean bifurcation ratio.

Zainab and Babatunde are partners in a haulage enterprise sharing profits and losses in the ratio of $3:2$ . Prior to the admission of Chijioke, their capital balances were $\text{₦}400,000$ and $\text{₦}300,000$ respectively. Upon admitting Chijioke to a $\frac{1}{5}$ share in the profits, the firm's assets were revalued, resulting in an appreciation of $\text{₦}80,000$ on machinery and a depreciation of $\text{₦}20,000$ on inventory. Additionally, goodwill was valued at $\text{₦}150,000$ , and Chijioke brought in his share of goodwill premium in cash to be distributed to the existing partners. What is the updated balance of Zainab's capital account immediately following these admission adjustments?

Cevabı ve açıklamayı göster

Cevap: 454000

Cevap

The updated balance of Zainab's capital account immediately following the admission adjustments is ₦454,000.

Zainab's capital account begins with ₦400,000. The net gain on revaluation (₦80,000 appreciation minus ₦20,000 depreciation = ₦60,000) is split in the old ratio of 3:2, adding ₦36,000 to her account. The goodwill premium paid by Chijioke is 1/5 of ₦150,000, which equals ₦30,000; Zainab receives 3/5 of this premium (₦18,000). Adding these yields an updated capital balance of ₦454,000.

Adım Adım Çözüm

1

Calculate the net gain or loss on revaluation of assets

Net Revaluation Gain = ₦80,000 - ₦20,000 = ₦60,000

Appreciation increases asset value while depreciation decreases it. The net figure represents total gain shared by existing partners.

2

Distribute the net revaluation gain to Zainab using the old profit sharing ratio

Zainab's Share of Revaluation Gain = 3/5 × ₦60,000 = ₦36,000

Revaluation gains belong to existing partners in their old profit sharing ratio.

3

Determine Chijioke's share of goodwill and allocate premium to Zainab

Goodwill Premium = 1/5 × ₦150,000 = ₦30,000; Zainab's Share = 3/5 × ₦30,000 = ₦18,000

The incoming partner pays premium for goodwill proportional to their profit share, which is credited to existing partners in their sacrificing ratio.

4

Sum Zainab's initial capital and all admission credits

Updated Capital Balance = ₦400,000 + ₦36,000 + ₦18,000 = ₦454,000

Capital accounts increase with revaluation gains and goodwill premium credits.

Musa, Emeka, and Audu are partners in a firm sharing profits and losses equally. Upon Audu's death, his capital account balance stands at $\text{₦}45,000$ . The revaluation of assets resulted in a profit where Audu's share is $\text{₦}5,000$ , and his share of goodwill is valued at $\text{₦}10,000$ . What is the total amount payable to Audu's executor?

Cevabı ve açıklamayı göster

Cevap: 60000

Cevap

The total amount payable to Audu's executor is

\text{₦}60,000

.

The total amount due to the deceased partner's executor is calculated by adding all credit adjustments (revaluation profit share and goodwill share) to the partner's opening capital balance:

\text{₦}45,000 + \text{₦}5,000 + \text{₦}10,000 = \text{₦}60,000

.

Adım Adım Çözüm

1

Add the deceased partner's initial capital balance, share of revaluation profit, and share of goodwill.

\text{₦}45,000 + \text{₦}5,000 + \text{₦}10,000 = \text{₦}60,000

When a partner dies, their capital account is credited with their balance of capital, share of asset revaluation profits, and share of goodwill before transferring the total amount to the executor's account.

Ebonyi Processing Company operates two departments: Milling and Bakery. During the financial year ended 31 December 2025, the Milling Department transferred flour to the Bakery Department at cost plus a mark-up of $33\frac{1}{3}\%$ . At the close of the year, the Bakery Department held closing inventory valued at $\text{N}120,000$ , of which $75\%$ represented flour transferred from the Milling Department. Calculate the amount of provision for unrealized profit on closing inventory to be recognized in the general profit and loss account.

Cevabı ve açıklamayı göster

Cevap: 22500

Cevap

The provision for unrealized profit to be recognized in the general profit and loss account is N22,500.

To calculate the provision for unrealized profit, first isolate the value of transferred stock in closing inventory:

75\% \times \text{N}120,000 = \text{N}90,000

. Next, convert the mark-up of

33\frac{1}{3}\%

(

\frac{1}{3}

) on cost to margin on transfer price:

\frac{1}{3+1} = \frac{1}{4}

(

25\%

). Multiplying the margin by the transferred stock value gives

25\% \times \text{N}90,000 = \text{N}22,500

.

Adım Adım Çözüm

1

Determine the value of transferred goods included in closing inventory

Transferred inventory = 75% * N120,000 = N90,000

Only the portion of inventory transferred internally contains unrealized profit.

2

Convert mark-up percentage on cost to margin percentage on transfer price

Margin = Mark-up / (1 + Mark-up) = (1/3) / (1 + 1/3) = 1/4 or 25%

Closing inventory is valued at transfer price (selling price), requiring margin to extract the profit element.

3

Calculate the provision for unrealized profit

Provision = 25% * N90,000 = N22,500

Unrealized profit is the profit margin embedded in unsold transferred inventory remaining at year-end.

A topographical map extract drawn at a scale of $1:50,000$ delineates a drainage basin. The total area of the basin measured on the map is $160\text{ cm}^2$ . Morphometric analysis reveals the following total stream segment lengths measured directly from the map across all stream orders:
- 1st-order stream segments: $48\text{ cm}$
- 2nd-order stream segments: $20\text{ cm}$
- 3rd-order stream segments: $12\text{ cm}$
- 4th-order stream segments: $8\text{ cm}$

Calculate the drainage density of the river basin in $\text{km/km}^2$ .

Cevabı ve açıklamayı göster

Cevap: 1.1

Cevap

The drainage density of the river basin is

1.1\text{ km/km}^2

.

Drainage density (

D

) measures the ratio of total stream channel length to the total drainage basin area (

D = \frac{\sum L}{A}

). Converting map measurements using the scale

1:50,000

(

1\text{ cm} = 0.5\text{ km}

), the total ground stream length is

88\text{ cm} \times 0.5\text{ km/cm} = 44\text{ km}

, and the actual ground area is

160\text{ cm}^2 \times (0.5)^2 = 40\text{ km}^2

. Dividing ground length by area produces

1.1\text{ km/km}^2

.

Adım Adım Çözüm

1

Determine linear ground scale from map scale

1\text{ cm on map} = 0.5\text{ km on ground}

Scale

1:50,000

means

1\text{ cm} = 50,000\text{ cm} = 500\text{ m} = 0.5\text{ km}

.

2

Calculate ground area of the basin

Basin Area

A = 40\text{ km}^2

Area conversion requires squaring the linear scale factor:

160\text{ cm}^2 \times (0.5\text{ km/cm})^2 = 160 \times 0.25 = 40\text{ km}^2

.

3

Calculate total actual stream length in the basin

Total Stream Length

\sum L = 44\text{ km}

Total map stream length

= 48 + 20 + 12 + 8 = 88\text{ cm}

. Ground length

= 88\text{ cm} \times 0.5\text{ km/cm} = 44\text{ km}

.

4

Compute Drainage Density (

D

)

D = 1.1\text{ km/km}^2

Drainage density is the total channel length divided by total basin area:

D = \frac{\sum L}{A} = \frac{44\text{ km}}{40\text{ km}^2} = 1.1\text{ km/km}^2

.

At the end of the financial year, a sole trader's trial balance extracted showed Trade Debtors of $₦80,000$ and an existing Provision for Doubtful Debts of $₦3,000$ . It was decided to write off an additional bad debt of $₦5,000$ and maintain a provision for doubtful debts at $5\%$ of the remaining trade debtors. What is the net amount of trade debtors to be presented in the Statement of Financial Position (Balance Sheet)?

Cevabı ve açıklamayı göster

Cevap: 71250

Cevap

The net trade debtors figure to be presented in the Balance Sheet is

₦71,250

.

To determine the net trade debtors figure in the Balance Sheet, unrecorded bad debts of

₦5,000

are first written off from gross debtors of

₦80,000

, resulting in adjusted debtors of

₦75,000

. The required closing provision for doubtful debts is

5\%

of

₦75,000

, which equals

₦3,750

. Subtracting this closing provision from adjusted debtors gives

₦75,000 - ₦3,750 = ₦71,250

.

A wildlife sanctuary occupies an area of $48\text{ cm}^2$ on a topographical map drawn at a scale of $1 : 100,000$ . If the map is reduced to a new scale of $1 : 400,000$ , what is the area of the sanctuary on the new map in $\text{cm}^2$ ?

Cevabı ve açıklamayı göster

Cevap: 3

Cevap

The area of the sanctuary on the reduced map is

3\text{ cm}^2

.

When a map scale is reduced from

1 : 100,000

to

1 : 400,000

, the linear dimension reduces by a factor of

4

(since

\frac{100,000}{400,000} = \frac{1}{4}

). Because area is two-dimensional, the area changes by the square of the linear reduction factor, which is

\left(\frac{1}{4}\right)^2 = \frac{1}{16}

. Therefore, the area on the new map is

48\text{ cm}^2 \times \frac{1}{16} = 3\text{ cm}^2

.

Adım Adım Çözüm

1

Determine the linear scale factor between the original and new scales

Linear scale factor =

\frac{\text{Original Scale Denominator}}{\text{New Scale Denominator}} = \frac{100,000}{400,000} = \frac{1}{4}

When a map scale changes from

1 : 100,000

to

1 : 400,000

, every linear dimension on the map is reduced to

\frac{1}{4}

of its original length.

2

Calculate the area reduction factor

Area scale factor =

\left(\frac{1}{4}\right)^2 = \frac{1}{16}

Map area scales as the square of the linear scale factor (

n^2

).

3

Calculate the new area on the reduced map

New Area =

48\text{ cm}^2 \times \frac{1}{16} = 3\text{ cm}^2

Multiplying the original area by the area scale factor gives the area representation on the new map.

Vanguard Enterprise Plc had an issued share capital of $1,000,000$ ordinary shares of $\text{₦}0.50$ each and a Share Premium account balance of $\text{₦}120,000$ . The company declared a bonus issue of $1$ new ordinary share for every $5$ shares held, utilizing the Share Premium account to fund the bonus shares. Immediately following the bonus issue, the company made a rights issue of $1$ new ordinary share for every $4$ shares held at an issue price of $\text{₦}0.80$ per share. What is the final balance of the Share Premium account (in $\text{₦}$ ) after both transactions are completed?

Cevabı ve açıklamayı göster

Cevap: 110000

Cevap

The final balance of the Share Premium account after both the bonus issue and rights issue is ₦110,000.

The correct final Share Premium balance is ₦110,000. Funding 200,000 bonus shares of ₦0.50 each requires ₦100,000 from the initial ₦120,000 premium, leaving ₦20,000. Subsequently, the 1-for-4 rights issue on the expanded 1,200,000 shares issues 300,000 shares at a premium of ₦0.30 per share (₦0.80 - ₦0.50), creating ₦90,000 of fresh premium. Summing the remaining ₦20,000 and ₦90,000 gives ₦110,000.

Adım Adım Çözüm

1

Calculate the bonus issue share quantity and nominal capital value

200,000 bonus shares with a total nominal value of ₦100,000

A 1-for-5 bonus issue on 1,000,000 shares yields 1,000,000 / 5 = 200,000 shares. At a nominal value of ₦0.50 each, the capital required is 200,000 × ₦0.50 = ₦100,000.

2

Deduct the capitalized amount from the initial Share Premium balance

Remaining Share Premium balance of ₦20,000

Initial Share Premium balance of ₦120,000 minus ₦100,000 capitalized for bonus shares leaves ₦20,000.

3

Determine the expanded share base and calculate the number of rights shares issued

300,000 rights shares issued

Post-bonus issued shares total 1,000,000 + 200,000 = 1,200,000 shares. A 1-for-4 rights issue gives 1,200,000 / 4 = 300,000 shares.

4

Compute the total share premium generated from the rights issue

₦90,000 in new share premium

Rights issue price is ₦0.80 per share while nominal value is ₦0.50, giving a premium of ₦0.30 per share. Total new premium created = 300,000 × ₦0.30 = ₦90,000.

5

Add the new rights issue premium to the remaining Share Premium balance

Total final Share Premium balance of ₦110,000

Remaining balance of ₦20,000 + ₦90,000 new premium = ₦110,000.

The closing debit balance of the Sales Ledger Control Account as at 31st December 2025 is

\text{₦}76,500

.

To find the closing debit balance of the Sales Ledger Control Account, sum all debit entries (Opening Balance

\text{₦}45,000

+ Credit Sales

\text{₦}185,000

+ Dishonoured Cheques

\text{₦}3,500

+ Cash Refunds

\text{₦}1,500

=

\text{₦}235,000

) and subtract all credit entries (Cash Received

\text{₦}142,000

+ Discount Allowed

\text{₦}4,800

+ Bad Debts

\text{₦}2,500

+ Returns Inwards

\text{₦}6,200

+ Contra Entry

\text{₦}3,000

=

\text{₦}158,500

). This gives

\text{₦}235,000 - \text{₦}158,500 = \text{₦}76,500

.

Adım Adım Çözüm

1

Calculate the total of the debit side entries

Total Debits =

\text{₦}45,000 + \text{₦}185,000 + \text{₦}3,500 + \text{₦}1,500 = \text{��}235,000

Opening debtors balance, credit sales, dishonoured cheques, and refunds to debtors increase the total debt owed by debtors and are placed on the debit side.

2

Calculate the total of the credit side entries

Total Credits =

\text{₦}142,000 + \text{₦}4,800 + \text{₦}2,500 + \text{₦}6,200 + \text{₦}3,000 = \text{₦}158,500

Payments received, discounts allowed, bad debts, sales returns, and set-off entries reduce the total debt owed by debtors and are placed on the credit side.

3

Subtract total credit items from total debit items to find the closing balance

Closing Debtors Balance =

\text{₦}235,000 - \text{₦}158,500 = \text{₦}76,500

The balancing figure on the credit side represents the closing debit balance brought down for the next accounting period.
