Question 3701Question →

Apex Zenith Ltd has an authorized share capital of $1,000,000$ ordinary shares of $₦1$ each, out of which $600,000$ shares are fully issued and paid up. The company also has $200,000$ , $5\%$ preference shares of $₦1$ each. For the year ended 31st December 2025, the net profit before appropriations was $₦150,000$ .

The directors resolved to:
- Transfer $₦30,000$ to General Reserve
- Pay preference share dividends in full
- Pay a $10\%$ dividend on ordinary shares

What is the balance of retained profit carried forward to the Statement of Financial Position?

₦50,000

₦10,000

₦60,000

₦90,000

Show answer & explanation

Answer: ₦50,000

Answer

The retained profit balance carried forward to the Statement of Financial Position is ₦50,000.

The retained profit carried forward is determined by deducting all profit appropriations (preference dividend of ₦10,000, ordinary dividend of ₦60,000 calculated on issued capital, and general reserve transfer of ₦30,000) from the net profit of ₦150,000, yielding ₦50,000.

Step-by-Step Solution

Calculate the preference dividend payable

5% of ₦200,000 preference shares = ₦10,000

Preference dividends are fixed obligations based on the paid-up preference share capital.

Calculate the ordinary dividend payable

10% of paid-up ordinary share capital (₦600,000) = ₦60,000

Dividends are computed exclusively on issued and paid-up share capital, not authorized capital.

Sum total appropriations of profit

₦10,000 (Preference Div) + ₦60,000 (Ordinary Div) + ₦30,000 (General Reserve) = ₦100,000

All distributions and allocations from net profit must be totaled.

Subtract total appropriations from net profit to determine retained profit

₦150,000 - ₦100,000 = ₦50,000

The undistributed portion of net profit is carried forward to equity in the balance sheet.

Along a sheltered coastline, longshore drift continuously transports beach sediments along the shoreline until a depositional ridge extends out and ties an offshore island directly to the mainland. Which of the following coastal landforms is formed by this process?

Oxbow lake

Tombolo

Scree slope

Metamorphic slate terrace

Show answer & explanation

Answer: Tombolo

Answer

The feature formed when a wave-deposited spit connects an offshore island to the mainland is called a tombolo.

A tombolo is formed when waves refract around an offshore island, creating a low-energy zone behind it. Longshore drift deposits sand and gravel in this zone, gradually building a spit that extends until it connects the mainland to the island.

Step-by-Step Solution

Identify the process and location described in the question.

The process is longshore drift and wave deposition occurring at a coastal margin.

Sediments are being moved along the shoreline and accumulated near an offshore island.

Analyze the landform resulting from connecting an offshore island to the mainland.

A depositional ridge of sand or gravel joining an island to the coast is defined as a tombolo.

As waves refract around the offshore island, low-energy deposition builds up sediment until it bridges the gap between the island and the main coastline.

Question 3708Question →

Arrange the following stages of coastal deposition and feature evolution in the correct chronological order, from the initial sediment transport mechanism to the final development of a sheltered wetland ecosystem.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with longshore drift carrying sediment along the coast, followed by the extension of a spit into open water, the curvature of the spit terminus into a hook due to wave refraction, and finally the settlement of fine silt behind the sheltered spit to form a salt marsh.

The formation of a coastal spit and its associated salt marsh follows a strict chronological sequence. Longshore drift first transports sand and shingle along the shoreline. As the sediment reaches an estuary or bay where wave energy drops, deposition occurs, causing a narrow landform (spit) to project into open water. Subsequent wave refraction or prevailing wind shifts curve the tip of the spit inland into a hook. Finally, in the quiet, low-energy water trapped behind the spit, fine silt and mud settle out, eventually colonizing with vegetation to form a salt marsh.

Step-by-Step Solution

Identify the primary sediment transport process.

Longshore drift moves littoral material along the coast toward a bay or river mouth.

Beach drift and longshore currents provide the continuous supply of sediment required for depositional landforms.

Determine the initial depositional feature formed as wave energy decreases.

A linear spit extends from the mainland out into open water.

When entering deeper, calmer water at a coastline indentation, waves lose energy and deposit their sediment load.

Identify how secondary marine forces modify the growing landform.

Wave refraction bends the distal end of the spit inland, forming a hook.

Refracted waves coming from dominant alternative directions alter the orientation of continued accretion at the tip.

Determine the final geomorphic and ecological development in the protected area.

Fine mud and organic material accumulate in the sheltered lagoon behind the spit to create a salt marsh.

The spit acts as a breakwater, creating a very low-energy marine micro-environment suitable for fine sediment deposition and halophytic plant colonization.

Question 3709Question →

In the industrial geography of Nigeria, major cement manufacturing plants are located near interior rural limestone deposits such as Ewekoro (Ogun State), Nkalagu (Ebonyi State), and Ashaka (Gombe State), whereas grain flour mills are predominantly concentrated in coastal port cities like Lagos and Port Harcourt. Which of the following statements best accounts for this spatial distribution of manufacturing industries?

Cement manufacturing involves heavy, weight-losing raw materials processed near limestone quarries to minimize bulk transport costs, whereas flour milling depends on imported raw wheat landed at ocean ports.

Cement manufacturing is a market-oriented industry sited near rural demand centers, while flour milling is a raw-material-oriented industry located near major domestic wheat plantations in the Niger Delta.

Cement factories require proximity to tin and columbite deposits found in southern coastal plains, while flour mills are sited near crude oil refining complexes located on the Jos Plateau.

Cement production requires perishable organic inputs that mandate immediate processing in dry savanna zones, whereas flour milling relies on non-perishable crops grown primarily in high-rainfall coastal rainforest belts.

Show answer & explanation

Answer: Cement manufacturing involves heavy, weight-losing raw materials processed near limestone quarries to minimize bulk transport costs, whereas flour milling depends on imported raw wheat landed at ocean ports.

Answer

Cement manufacturing is located near interior limestone quarries because limestone is a heavy, weight-losing raw material, whereas wheat flour milling is sited at coastal port cities to minimize the transport costs of imported raw wheat.

The locational disparity between cement manufacturing and flour milling in Nigeria is governed by raw material weight characteristics and transport geography. Cement manufacture uses limestone, a bulky mineral that loses substantial weight during processing into clinker and finished cement. Under Weber's least-cost location principles, processing weight-losing inputs near their quarry sites (such as Ewekoro in Ogun State, Nkalagu in Ebonyi State, or Ashaka in Gombe State) minimizes long-distance freight costs for heavy waste matter. Conversely, Nigerian flour mills rely primarily on imported raw wheat brought in by sea transport. Siting flour mills directly at coastal port facilities like Lagos and Port Harcourt minimizes handling and transport expenses by processing grain right at the point of import entry.

Step-by-Step Solution

Analyze raw material characteristics for cement production

Limestone, clay, and gypsum used in cement making are bulky and lose significant weight during calcination and clinker formation.

According to Weber's Industrial Location Theory, weight-losing raw material processing must occur near the source to avoid transporting useless waste mass.

Analyze raw material sourcing for flour milling in Nigeria

Commercial wheat flour mills in Nigeria rely heavily on imported hard wheat grain arriving via maritime bulk carriers.

Locating flour mills at port terminals (Lagos, Port Harcourt, Calabar) eliminates inland freight charges for unprocessed heavy grain.

Synthesize the spatial locational contrast

Cement plants are raw-material-oriented near interior quarry sites (Ewekoro, Nkalagu, Ashaka), while flour mills are port-oriented to intercept imported raw materials.

This dual pattern reflects optimal transport cost minimization based on material source locations.

A surplus of

\$3\text{ billion}

A deficit of

\$4\text{ billion}

A surplus of

\$5\text{ billion}

Show answer & explanation

Answer: A surplus of $\$4\text{ billion}$

Answer

The nation's balance of visible trade is a surplus of

\$4\text{ billion}

The balance of visible trade considers only tangible physical commodities. Subtracting the value of visible imports (manufactured machinery at

\$8\text{ billion}

) from visible exports (crude oil at

\$12\text{ billion}

) yields a trade surplus of

\$4\text{ billion}

. Invisible items such as tourism receipts and shipping charges are excluded.

Step-by-Step Solution

Identify visible trade items (tangible merchandise)

Visible exports = crude oil (

\$12\text{ billion}

); Visible imports = manufactured machinery (

\$8\text{ billion}

Visible trade accounts exclusively for tangible physical commodities, excluding services such as shipping, insurance, and tourism.

Calculate the balance of visible trade

\text{Balance of Visible Trade} = \$12\text{ billion} - \$8\text{ billion} = +\$4\text{ billion}

Match each company reserve in Column A with its correct definition and statutory characteristic in Column B.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Share Premium Account matches statutory capital reserve arising from issuing shares above par value; Revaluation Reserve matches unrealized capital reserve created from revaluation of non-current assets; General Reserve matches revenue reserve set aside out of distributable profits for general future needs; Retained Earnings matches accumulated revenue reserve comprising profit after tax available for distribution.

Each reserve item is paired according to company accounting rules: Share Premium is a capital reserve restricted by law to specific uses like bonus share issues; Revaluation Reserve represents unrealized gains on non-current assets; General Reserve is a revenue reserve set aside from earned profits for general stability; Retained Earnings represents accumulated undistributed net profits available for dividend declaration.

Step-by-Step Solution

Distinguish between Capital Reserves and Revenue Reserves

Capital reserves (Share Premium, Revaluation Reserve) are created from non-trading sources or statutory restrictions and cannot be distributed as cash dividends. Revenue reserves (General Reserve, Retained Earnings) are created from trading profits and are available for dividends.

Understanding the source and legal restrictions of reserves determines their classification.

Identify the specific nature of each Capital Reserve

Share Premium comes from issuing shares above par value and has legally restricted uses. Revaluation Reserve records unrealized gains on asset revaluation.

Share Premium is governed by statutory usage provisions, whereas asset appreciation forms revaluation surplus.

Identify the specific nature of each Revenue Reserve

General Reserve is an intentional allocation of profit to bolster financial strength, while Retained Earnings is the unappropriated balance of cumulative net income.

General Reserve requires a specific transfer entry, whereas Retained Earnings carries over accumulated residual profit.

During a mapwork exercise on a topographical map with a scale of $1 : 100,000$ , a student identifies a river bed at an elevation of $120\text{ m}$ and a hilltop trigonometric station at an elevation of $320\text{ m}$ . If the map distance between these two points is $4\text{ cm}$ , what is the average gradient of the slope?

1 \text{ in } 20

1 \text{ in } 50

1 \text{ in } 12.5

1 \text{ in } 2

Show answer & explanation

Answer: $1 \text{ in } 20$

Answer

The average gradient of the slope is

1 \text{ in } 20

The slope gradient is calculated by taking the ratio of Vertical Interval (VI) to Horizontal Equivalent (HE). The vertical rise between the river bed and the trigonometric station is

320\text{ m} - 120\text{ m} = 200\text{ m}

. Using the map scale of

1 : 100,000

, a map distance of

4\text{ cm}

corresponds to

400,000\text{ cm}

4,000\text{ m}

on ground. Dividing

200\text{ m}

4,000\text{ m}

yields

\frac{1}{20}

, which is expressed as

1 \text{ in } 20

Step-by-Step Solution

Calculate the Vertical Interval (VI)

\text{VI} = 320\text{ m} - 120\text{ m} = 200\text{ m}

Vertical interval is the difference in height between the higher point and the lower point.

Calculate the Horizontal Equivalent (HE) in real-world meters using the map scale

\text{HE} = 4\text{ cm} \times 100,000 = 400,000\text{ cm} = 4,000\text{ m}

To find actual ground distance, multiply the map distance by the scale denominator and convert centimeters to meters.

Compute the gradient ratio

\text{Gradient} = \frac{\text{VI}}{\text{HE}} = \frac{200\text{ m}}{4,000\text{ m}} = \frac{1}{20} = 1 \text{ in } 20

Gradient is expressed as a ratio of vertical rise to horizontal distance.

To channel wind currents directly into the cabinet to measure wind velocity with an internal anemometer

Show answer & explanation

Answer: To reflect solar radiation and allow free air circulation while protecting instruments from direct sunlight and precipitation

Answer

The white paint reflects incoming solar radiation to avoid heating the interior, and the double-louvered sides allow free air movement while shielding instruments like thermometers from direct sunlight and rain.

The Stevenson screen is painted white to reflect solar radiation and prevent the enclosure from heating up above ambient shade temperature. The double-louvered sides permit natural air movement while shielding the thermometers inside from direct sunlight, wind gusts, and rain.

Step-by-Step Solution

Identify the purpose of a Stevenson screen in a weather station.

A Stevenson screen is designed to shield temperature and humidity instruments from direct solar heat, rain, and ground radiation while allowing ambient air to circulate freely.

Accurate weather measurement requires measuring shade air temperature and natural relative humidity.

Evaluate the function of white paint and louvered sides.

White paint reflects sunlight (high albedo), preventing the box from absorbing heat. Louvered sides act like blinds, letting air flow through while blocking direct light and precipitation.

This setup ensures the instruments measure true ambient atmospheric conditions without radiation bias.

Push factor: high demand for seasonal labor on cash-crop plantations; Pull factor: prolonged dry season and limited rural income

Push factor: abundance of fertile forest soils and minerals; Pull factor: high prevalence of tsetse flies and crop diseases

Push factor: nucleated rural settlement layouts along transport routes; Pull factor: dispersed farmstead patterns in river valleys

Show answer & explanation

Answer: Push factor: prolonged dry season and limited rural income; Pull factor: high demand for seasonal labor on cash-crop plantations

Answer

Push factor: prolonged dry season and limited rural income; Pull factor: high demand for seasonal labor on cash-crop plantations

The correct answer accurately identifies that prolonged dry season hardship and lack of income in the interior savanna force workers out of their origin (push factor), while cocoa and coffee plantation labor demands draw them to coastal destinations (pull factor).

Step-by-Step Solution

Analyze the unfavorable origin conditions in the interior savanna.

Identify that the long dry season (Harmattan period) prevents year-round farming and creates rural unemployment, acting as a push factor.

Push factors are negative conditions at the place of origin that compel people to move away.

Analyze the favorable destination conditions in the coastal forest belt.

Identify that expanding cocoa, coffee, and oil palm plantations require extra seasonal labor, acting as a pull factor.

Pull factors are attractive opportunities at the destination that draw migrants in.

Match the identified factors to the corresponding migration classifications.

Confirm that dry season income lack (push) and coastal farm employment demand (pull) correctly describe the regional migration flow.

Accurate demographic analysis requires distinguishing negative push conditions from positive pull incentives.

₦80,000

₦88,000

₦98,000

₦106,000

Show answer & explanation

Answer: ₦98,000

Answer

The total purchases figure for the year is ₦98,000.

The correct answer (₦98,000) is determined by reconstructing the Total Creditors Control Account to find credit purchases, then adding cash purchases. Sum of debit entries in the creditors control account is ₦68,000 + ₦2,000 + ₦3,000 + ₦22,000 = ₦95,000. Subtracting the opening balance of ₦15,000 yields credit purchases of ₦80,000. Adding cash purchases of ₦18,000 yields ₦98,000.

Step-by-Step Solution

Calculate credit purchases by preparing the Total Creditors Control Account.

Credit Purchases = ₦68,000 (Payments) + ₦2,000 (Discount Received) + ₦3,000 (Returns Outwards) + ₦22,000 (Closing Creditors) - ₦15,000 (Opening Creditors) = ₦80,000.

Debits to the Total Creditors Account include payments made, discounts received, returns outwards, and the closing balance. Deducting the opening credit balance gives the credit purchases for the period.

Calculate total purchases by adding cash purchases to credit purchases.

Total Purchases = Credit Purchases (₦80,000) + Cash Purchases (₦18,000) = ₦98,000.

Total purchases consist of all goods bought during the accounting period, whether paid for immediately in cash or acquired on credit.

In a manufacturing firm producing leather footwear, various expenses are incurred during the production process. Which of the following costs is classified as a direct expense and included in the calculation of Prime Cost?

Royalties paid to a designer based on the specific number of units produced

Salary paid to the factory quality control supervisor

Carriage outwards paid for delivering finished footwear to distributors

Cost of purchasing a new industrial leather-cutting machine

Show answer & explanation

Answer: Royalties paid to a designer based on the specific number of units produced

Answer

Royalties paid to a designer based on the specific number of units produced

Royalties paid per unit produced are direct expenses because they can be traced completely to individual manufactured items. Adding direct expenses to direct materials and direct labor gives Prime Cost.

Step-by-Step Solution

Understand the components of Prime Cost

Prime Cost consists of direct materials, direct labor, and direct expenses.

Prime Cost includes all expenditure directly traceable to the physical unit of production.

Identify the nature of direct expenses

Direct expenses are expenses other than direct materials and direct labor incurred specifically for a particular product or batch (e.g., royalties paid per unit produced or specialized equipment hire).

Royalties paid on a per-unit basis can be directly attributed to each item manufactured.

Differentiate direct expenses from indirect manufacturing overheads and non-manufacturing costs

Factory supervisor salary is indirect labor (factory overhead); carriage outwards is a selling expense; machinery purchase is capital expenditure.

Only royalties paid per unit manufactured meet the strict definition of direct expenses.

Arrange the following major Nigerian seaports in geographical sequence along the coast, starting from the westernmost port to the easternmost port:

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence from west to east is Tin Can Island Port (Lagos), Warri Port (Delta State), Port Harcourt Complex (Rivers State), and Calabar Port (Cross River State).

Nigeria's major seaports are aligned along the southern coastline from west to east as follows: Tin Can Island Port in Lagos State occupies the far west; Warri Port in Delta State serves the western Niger Delta; Port Harcourt Complex in Rivers State serves the eastern Niger Delta; and Calabar Port in Cross River State anchors the easternmost maritime outlet near the Cameroonian border.

Step-by-Step Solution

Identify the coastal state and longitude of each seaport.

Tin Can Island Port is in Lagos State (west), Warri Port is in Delta State (mid-west), Port Harcourt Complex is in Rivers State (south-east), and Calabar Port is in Cross River State (far east).

Geographical positioning determines the relative longitudinal order along Nigeria's Gulf of Guinea coastline.

Position the westernmost port.

Tin Can Island Port in Lagos occupies the westernmost position among the listed ports.

Lagos State forms the western maritime boundary of Nigeria adjacent to the Republic of Benin.

Trace eastwards through the Niger Delta ports.

Moving east from Lagos leads first to Warri Port in Delta State, followed by Port Harcourt Complex along the Bonny River in Rivers State.

Delta State lies west of Rivers State along the Niger Delta coast.

Identify the easternmost terminus port.

Calabar Port in Cross River State occupies the easternmost position.

Cross River State represents Nigeria's easternmost coastal state bordering Cameroon.
