Match each bank-related transaction on the left to its correct accounting treatment on the right during the preparation of an Adjusted Cash Book and Bank Reconciliation Statement.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Standing order payments are credited to the Adjusted Cash Book; direct customer deposits are debited to the Adjusted Cash Book; issued cheques not yet cleared are treated as unpresented cheques in the Bank Reconciliation Statement; and deposited cheques not yet credited are treated as uncredited deposits in the Bank Reconciliation Statement.

Standing orders represent unrecorded cash payments and are credited to the Adjusted Cash Book. Direct customer deposits represent unrecorded cash receipts and are debited to the Adjusted Cash Book. Unpresented cheques and uncredited deposits are timing differences and are placed in the Bank Reconciliation Statement.

Step-by-Step Solution

1

Identify items that require Cash Book adjustment

Standing orders and direct deposits are unrecorded bank transactions that must be entered into the Cash Book before reconciliation.

The Cash Book must reflect all actual bank transactions (charges, interest, direct debits, standing orders, and credit transfers) prior to reconciling timing differences.

2

Determine debit/credit entries for Adjusted Cash Book items

Direct customer deposits increase cash (debit entry); standing order insurance payments decrease cash (credit entry).

Cash Book follows double-entry rules where cash receipts are debited and cash payments are credited.

3

Identify timing differences for the Bank Reconciliation Statement

Unpresented cheques and uncredited deposits are placed directly into the Bank Reconciliation Statement.

Timing differences occur due to time lags in bank processing and are already recorded in the Cash Book, so they do not alter the Adjusted Cash Book balance.

Key Concept

Distinguishing between items that adjust the Cash Book (unrecorded transactions and cash book errors) and items that belong in the Bank Reconciliation Statement (timing differences such as unpresented cheques and uncredited lodgements).

Click a left item, then click its matching right item

Show answer & explanation

Answer

Jos Plateau corresponds to the high basement complex dome with radial drainage; Biu Plateau corresponds to the basaltic volcanic plateau forming a watershed for Hawal and Gongola rivers; Sokoto Plains corresponds to the sedimentary basin with cuestas drained by the Rima system; and Cross River Basin corresponds to the structural lowland trough drained from the Oban Hills and Western Cameroon highlands.

Each physical region in Nigeria possesses a unique combination of rock geology and drainage patterns: the Jos Plateau is a basement dome with radial drainage; the Biu Plateau is a volcanic basaltic upland; the Sokoto Plains consist of sedimentary cuestas drained by the Rima; and the Cross River Basin is a lowland trough fed by the Oban Hills and Cameroon highlands.

Step-by-Step Solution

1

Identify the drainage and geological features of the Jos Plateau.

Recognize that the Jos Plateau is an elevated basement complex mass from which rivers flow outwards in all directions (radial pattern) toward the Niger, Benue, and Lake Chad basins.

Topographical elevation and crystalline rock structure make it the country's primary hydrographic apex.

2

Identify the origin and drainage traits of the Biu Plateau.

Determine that unlike the basement complex plates, Biu is a basaltic volcanic plateau feeding regional tributaries like River Hawal.

Cenozoic volcanic activity created distinct basalt caprocks distinguishing it from granitic uplands.

3

Analyze the rock structure and landforms of the Sokoto Plains.

Associate the northwestern plains with Cretaceous-Tertiary sedimentary strata, cuesta ridges, and the Rima-Sokoto river network.

The Iullemmeden sedimentary basin structure dictates the low-gradient dip slopes and cuesta scarp topography.

4

Evaluate the coastal/southeastern interior relief of the Cross River Basin.

Link the Cross River depression to sedimentary infill bounded by the Oban Hills and Cameroon mountain ranges.

High rainfall and elevated source ranges feed heavily silted streams flowing into the Cross River estuary.

) and double rainfall maxima.

Equatorial regions lie along the equator, experiencing constant insolation and twice-yearly ITCZ zenithal rain.

2

Analyze Tropical Continental (Savanna) characteristics

Identified alternating wet and dry seasons following ITCZ migration.

As the ITCZ moves northwards or southwards, rain-bearing maritime air masses are replaced by dry continental air masses.

3

Analyze Mediterranean Climate characteristics

Identified winter precipitation driven by Westerlies and dry summers.

The seasonal shift of wind belts brings prevailing Westerly winds to northern and southern continental extremities in winter.

4

Analyze Tropical Desert Climate characteristics

Identified extreme diurnal temperature ranges and annual rainfall under

250\text{ mm}

.

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

1

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.

2

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.

3

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.

Question 570Question →

Match each topographic map elevation scenario to its corresponding calculated slope gradient ratio ( $1 \text{ in } N$ ). Which of the following correct pairs match each map measurement scenario on the left with its computed gradient ratio on the right?

Click a left item, then click its matching right item

Show answer & explanation

Answer

The correct matches pair each scenario with its gradient ratio as follows: the

80\text{ m}

elevation difference over

4\text{ cm}

(

1:50,000

) matches

1 \text{ in } 25

; the

150\text{ m}

elevation difference over

3\text{ cm}

(

1:100,000

) matches

1 \text{ in } 20

; the

200\text{ m}

elevation difference over

2\text{ cm}

(

1:25,000

) matches

1 \text{ in } 2.5

; and the

60\text{ m}

elevation difference over

6\text{ cm}

(

1:50,000

) matches

1 \text{ in } 50

.

Each elevation difference (VI) is divided by the true ground distance (HE) converted to meters. For scenario 1:

4\text{ cm} \times 50,000 / 100 = 2,000\text{ m}

, leading to

80 / 2,000 = 1 / 25

. For scenario 2:

3\text{ cm} \times 100,000 / 100 = 3,000\text{ m}

, giving

150 / 3,000 = 1 / 20

. For scenario 3:

2\text{ cm} \times 25,000 / 100 = 500\text{ m}

, giving

200 / 500 = 1 / 2.5

. For scenario 4:

6\text{ cm} \times 50,000 / 100 = 3,000\text{ m}

, yielding

60 / 3,000 = 1 / 50

.

Step-by-Step Solution

1

Recall the gradient formula for topographic maps

Gradient formula is

\text{Gradient} = \frac{\text{Vertical Interval (VI)}}{\text{Horizontal Equivalent (HE)}}

, where both VI and HE must be expressed in the same units (meters).

Gradient is a dimensionless ratio comparing vertical rise to horizontal ground distance.

2

Calculate Horizontal Equivalent (HE) for each scenario

Scenario 1:

\text{HE} = 4\text{ cm} \times 50,000 = 200,000\text{ cm} = 2,000\text{ m}

. Scenario 2:

\text{HE} = 3\text{ cm} \times 100,000 = 300,000\text{ cm} = 3,000\text{ m}

. Scenario 3:

\text{HE} = 2\text{ cm} \times 25,000 = 50,000\text{ cm} = 500\text{ m}

. Scenario 4:

\text{HE} = 6\text{ cm} \times 50,000 = 300,000\text{ cm} = 3,000\text{ m}

.

Map distance must be converted to actual ground distance using the representative fraction scale.

3

Compute the gradient ratio (VI / HE) for each item and pair with the correct ratio

Item 1:

\frac{80}{2000} = \frac{1}{25}

(

1 \text{ in } 25

). Item 2:

\frac{150}{3000} = \frac{1}{20}

(

1 \text{ in } 20

). Item 3:

\frac{200}{500} = \frac{1}{2.5}

(

1 \text{ in } 2.5

). Item 4:

\frac{60}{3000} = \frac{1}{50}

(

1 \text{ in } 50

).

Simplifying each fraction to unit numerator format (

1 / N

) yields the standard gradient ratio expression.

Question 571Question →

Match each drainage basin morphometric property listed on the left with its corresponding geomorphic or hydrological significance on the right.

Click a left item, then click its matching right item

Show answer & explanation

Answer

High Drainage Density matches with highly impermeable surface rocks, steep relief, and fine drainage texture; High Bifurcation Ratio matches with strong structural geological control; High Form Factor matches with a circular basin shape leading to concentrated runoff and sharp peak floods; Low Stream Frequency matches with permeable underlying rock, high infiltration capacity, and coarse drainage texture.

High Drainage Density matches impermeable rocks and steep relief because runoff forms numerous channels. High Bifurcation Ratio indicates structural geological controls such as faulting. High Form Factor denotes a circular basin producing concentrated tributary runoff and sharp flood peaks. Low Stream Frequency corresponds to permeable rock where infiltration reduces stream channel generation.

Step-by-Step Solution

1

Examine the physical controls on Drainage Density (

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

) and Stream Frequency (

F_s = \frac{N}{A}

).

High drainage density occurs when surface runoff is high and infiltration is low due to impermeable rock and steep slopes. Conversely, low stream frequency indicates high surface permeability where water infiltrates underground rather than forming channels.

Understanding surface runoff dynamics and bedrock permeability.

2

Analyze the geomorphic implication of the Bifurcation Ratio (

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

).

While values between 3 and 5 are typical in hydrogeologically uniform basins, values significantly higher than 5 reflect tectonic or structural geological distortion such as faulting.

Identifying structural controls in river network organization.

3

Relate Basin Form Factor (

F_f = \frac{A}{L^2}

) to basin geometry and flood hydrographs.

Form factors approaching 1 describe circular basins where tributaries feed into the main trunk stream at similar travel times, yielding a sharp, high peak discharge.

Evaluating how basin shape governs runoff timing and flood risk.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Factory supervisor's salary matches Factory Overhead (Indirect Labor Cost); Depreciation of factory plant and machinery matches Factory Overhead (Indirect Expense); Carriage inwards on raw materials matches Prime Cost (Direct Material Cost); Sales manager's commission matches Selling and Distribution Expense.

Factory overheads include all indirect manufacturing expenses incurred in the factory building, such as indirect labor (factory supervisor salary) and indirect factory operational costs (depreciation of factory machinery). Direct costs related to raw material acquisition (carriage inwards) increase prime cost, whereas post-production expenses (sales commission) belong to administrative or selling expenses.

Step-by-Step Solution

1

Identify factory overheads (indirect manufacturing costs)

Factory supervisor's salary is categorized as indirect labor, while depreciation of factory machinery is categorized as an indirect factory expense.

Indirect costs incurred within the production environment that cannot be conveniently assigned to specific units produced constitute factory overheads.

2

Identify prime cost components

Carriage inwards on raw materials is added to the cost of raw materials purchased.

Carriage inwards forms an integral part of the direct material cost required to bring raw materials to their present location and condition.

3

Distinguish manufacturing costs from selling expenses

Sales manager's commission is classified as a selling and distribution expense.

Expenses connected with the sale and distribution of finished goods are charged directly to the Profit and Loss Account rather than the Manufacturing Account.

Key Concept

Show answer & explanation

Answer

Accumulated Fund matches with 'Equivalent to owner's capital, representing the net assets of the organization'; Income and Expenditure Account matches with 'Prepared on an accrual basis to measure operational surplus or deficit'; Receipts and Payments Account matches with 'A summary cash account recording all cash inflows and outflows regardless of period'; Subscriptions matches with 'Regular recurring membership fees serving as the main source of operational revenue'.

Each item accurately pairs the non-profit financial component with its primary feature: Accumulated Fund represents net asset capital, Income and Expenditure Account measures accrual-based surplus/deficit, Receipts and Payments Account summarizes cash activity, and Subscriptions provide recurring membership revenue.

Step-by-Step Solution

1

Identify the nature of equity in non-profit organizations

Accumulated Fund is identified as total assets minus total liabilities, taking the place of Capital in profit-making entities.

Non-profit organizations do not have owners or share capital, so equity is retained as accumulated surplus.

2

Analyze the financial statements used by non-profit organizations

The Income and Expenditure Account uses accrual concepts to derive surplus/deficit, while the Receipts and Payments Account is a pure cash summary.

Distinguishing between cash-basis summaries and accrual-basis performance accounting is essential for financial reporting.

3

Determine the role of member contributions

Subscriptions represent recurring revenue receipts from members.

Subscriptions fund day-to-day operations and are recorded in the Income and Expenditure Account after adjusting for prepaid/accrued balances.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Mediterranean climate matches alternating summer subtropical high-pressure and winter westerlies; Tropical Wet-and-Dry climate matches seasonal ITCZ movement; Temperate Continental climate matches extreme thermal continentality; Marine West Coast climate matches year-round onshore westerlies.

Each climate type corresponds directly to its dominant atmospheric driver: Mediterranean climate matches summer subtropical highs and winter westerlies; Tropical Wet-and-Dry matches seasonal ITCZ shifts; Temperate Continental matches landmass continentality; and Marine West Coast matches persistent onshore westerlies.

Step-by-Step Solution

1

Analyze the atmospheric mechanisms controlling Mediterranean climates.

Summer drought is caused by the poleward shift of subtropical anticyclones, while winter rainfall originates from cyclonic depressions embedded in shifting westerly winds.

Seasonal migration of global pressure belts alters dominant air masses over

30^\circ\text{--}40^\circ

western continental margins.

2

Determine the atmospheric driver for Tropical Wet-and-Dry (Savanna) environments.

Precipitation alternates between heavy convective summer rain under the ITCZ and prolonged winter dry conditions when trade winds dominate.

The thermal equator and ITCZ track maximum solar zenith across tropical latitudes.

3

Evaluate the primary control over Temperate Continental (Subarctic) climatic extremes.

Distance from oceans leads to rapid land surface heating and cooling, yielding massive seasonal temperature ranges and intense winter cold.

Land masses have a lower specific heat capacity than marine water bodies.

4

Identify the oceanic control on Marine West Coast regions.

Continuous onshore westerly flow supplies frequent maritime polar air masses, keeping summer temperatures cool, winter temperatures mild, and precipitation well distributed throughout the year.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Royalty paid per unit of item produced matches with direct expense in Prime Cost; Factory supervisor's salary and plant depreciation matches with indirect manufacturing costs under Factory Overheads; Net decrease in Work-in-Progress matches with being added to Prime Cost and Factory Overheads; Carriage inwards on raw materials matches with being added to direct materials cost to find cost of raw materials consumed.

Each item is correctly matched according to standard cost accounting rules for manufacturing accounts: Carriage inwards adds to raw materials cost, royalties form part of direct expenses within Prime Cost, supervisory salaries and plant depreciation are factory overheads, and a net decrease in WIP increases the overall cost of production.

Step-by-Step Solution

1

Classify direct costs

Identify that raw material carriage inwards increases the raw material purchase cost, while unit-based production royalties are direct expenses forming part of Prime Cost.

Direct costs are expenses directly traceable to the unit of output.

2

Classify indirect costs

Group factory supervisor salaries and plant depreciation into Factory Overheads.

Indirect manufacturing costs support production but cannot be assigned directly to individual units.

3

Apply Work-in-Progress adjustment rules

Determine that a net decrease in WIP (

Opening\ WIP > Closing\ WIP

) represents additional cost absorbed during the period, thereby increasing the Cost of Production.

Cost of Production = Prime Cost + Factory Overheads + Opening WIP - Closing WIP.

Mediterranean climates rely on pressure belt oscillations, Tropical Monsoons depend on seasonal thermal wind shifts, Subarctic climates are controlled by high-latitude polar air masses, and Hot Deserts are maintained by subtropical high-pressure subsidence.

Step-by-Step Solution

1

Analyze the pressure belt shift associated with Mediterranean (Cs) climate zones.

Identify that dry summers stem from subtropical highs and moist winters stem from mid-latitude westerlies.

Mediterranean climates are geographically situated between 30° and 40° latitude, subject to shifting wind systems.

2

Examine atmospheric mechanisms driving Tropical Monsoon (Am) systems.

Link monsoon regimes to land-sea thermal differentials and seasonal wind shifts.

Differential heating between continents and oceans drives the seasonal inflow of moist air.

3

Evaluate high-latitude climate dynamics for Subarctic (Dfc) conditions.

Associate continental polar air mass dominance with long, severe cold seasons.

High latitude and continentality limit insolation and trap cold continental air masses.

4

Identify the primary climatic control forming Hot Deserts (BWh).

Connect low annual precipitation with subtropical high-pressure cell subsidence.

Descending air suppresses convection and cloud formation in trade wind desert regions.

Match each accounting adjustment scenario at the end of the financial year with its correct treatment in the Profit and Loss Account and Balance Sheet of a sole trader.

Click a left item, then click its matching right item

Show answer & explanation

Answer

Accrued Expense matches with 'Added to the relevant expense in the Profit and Loss Account and shown as a Current Liability in the Balance Sheet'. Prepaid Expense matches with 'Deducted from the relevant expense in the Profit and Loss Account and shown as a Current Asset in the Balance Sheet'. Accrued Income matches with 'Added to the relevant income in the Profit and Loss Account and shown as a Current Asset in the Balance Sheet'. Prepaid Income matches with 'Deducted from the relevant income in the Profit and Loss Account and shown as a Current Liability in the Balance Sheet'.

Each item is correctly classified by matching the P&L adjustment direction (adding for accruals, deducting for prepayments) with its proper position in the Balance Sheet (liability for expense accruals and income prepayments; asset for expense prepayments and income accruals).

Step-by-Step Solution

1

Apply the accrual accounting concept to expenses.

Expenses incurred during the period must be matched against revenues earned regardless of cash paid. Owing amounts (accruals) are added to expenses (increasing P&L charge) and recognized as current liabilities. Amounts paid in advance (prepayments) are deducted from expenses and recognized as current assets.

Accruals reflect obligations to pay; prepayments reflect future economic benefits.

2

Apply the accrual accounting concept to incomes.

Revenue earned but not yet received (accrued income) increases total income in P&L and is a receivable (current asset). Revenue received in advance (prepaid income) belongs to the subsequent period, so it is removed from current P&L income and treated as an obligation to deliver services/goods (current liability).

Revenue recognition depends on performance/earning, not cash collection timing.
