ALJUNIED · SECONDARY 3 · G3 PRINCIPLES OF ACCOUNTS · WEEKDAY OR WEEKEND
Secondary 3 POA tuition in Aljunied should teach students why goods sold and stock remaining need separate records. The 2027 SEC G3 K342 syllabus includes FIFO calculation and inventory impairment when net realisable value is lower than cost.
An original fictional trading business begins with goods costing $11, buys newer units for $13, sells 230 packs and discovers ten damaged items at the reporting date. The full solution connects a $2,790 FIFO cost of sales, $50 impairment, $860 ending stock and $800 simplified profit.
For parents deciding on weekday or weekend tuition, a narrow FIFO-layer error may need a focused after-school repair. A complete stock valuation and adjusted profit explanation may benefit from a longer rested session.
Did you know? The inventory count remains seventy packs even after its reported value falls by $50. A write-down of money value is not a disappearance of physical stock.
Start with the physical stock and purchase layers
Track opening and new stock at their correct FIFO costs, then value each item remaining at the lower of cost and net realisable value. Only after that should the pupil explain the impairment journal and final profit.

CHAPTER 1 OF 15
What the 2027 G3 inventory topic actually asks students to do
Secondary 3 Principles of Accounts (POA) tuition in Aljunied should help an elective student represent the movement of goods correctly before learning to prepare polished financial statements. SEAB’s 2027 SEC G3 K342 syllabus expressly covers the perpetual recording of purchases and sales, FIFO calculation of cost of sales and ending inventory, and impairment when net realisable value falls below inventory cost.
The published G2 K233 syllabus is a separate upper-secondary course. Parents should use the child’s actual enrolled level, examination year and school teaching sequence when choosing exercises; a G3 case should not be treated as automatically suitable for every student labelled ‘POA’.
The practical idea is that the number of goods purchased is not the same as the number sold. Inventory has an original cost basis; products sold leave inventory and enter Cost of Sales, while goods still held may need a reporting-date valuation.
FIFO, or first-in, first-out, matters when goods were acquired at different prices. A student who simply multiplies all sold items by the most recent cost may misstate Cost of Sales and the unsold inventory even if the number of units is correct.
Valuation then introduces a second question. Some stock may be damaged or become less realisable than its recorded cost. A truthful report should not continue showing a higher value when the supplied net realisable value is lower.
A useful tutor should ask the learner to explain the physical warehouse movement and the change in economic value before giving a ledger template. The exact first mistake may be FIFO ordering, a cost-versus-selling-price confusion or misunderstanding how a write-down affects profit.
The fictional Aljunied learning-materials trader in this guide is a teaching business, not a shop that operates in the neighbourhood. Its customer sales, damaged inventory, expenses and values are invented for accurate practice.
Good accounting instruction makes each amount traceable to the business event, and makes room to say when an assumption is unknown rather than conceal uncertainty.
CHAPTER 2 OF 15
Full original FIFO and damaged-inventory case for one financial year
Imagine a fictional Aljunied learning-materials trader that sells one type of illustrated paper-learning pack. The business starts a financial year with one hundred packs left from a previous purchase, each costing $11. Opening Inventory therefore contains one hundred units valued at $1,100.
During the current year the trader receives two hundred further packs at a cost of $13 per unit. Assume every new pack is acquired on credit and no delivery cost, discount, return or other purchase charge applies. The new inventory purchase is 200 × $13 = $2,600.
Goods available for sale are the opening one hundred plus the purchased two hundred, totalling three hundred units. Their combined recorded cost is $1,100 + $2,600 = $3,700. That total should be understood as resources available, not automatically as cost of goods already sold.
The trader delivers 230 packs to customers during this one financial year, charging $19 each on credit. Assume no sales returns and that the revenue criteria under the course are met when the goods are delivered. Sales Revenue is 230 × $19 = $4,370.
Because FIFO is specified, the one hundred opening packs at $11 are treated as sold first. They contribute 100 × $11 = $1,100 to the Cost of Sales calculation. The remaining 130 sold packs are drawn from the newer $13 layer, contributing 130 × $13 = $1,690.
Total Cost of Sales recognised when the 230 items are delivered is $1,100 + $1,690 = $2,790. A pupil who takes 230 × $13 obtains $2,990, incorrectly ignoring the earlier lower-cost inventory. The inventory count may be right while its cost valuation is wrong.
Seventy packs remain physically at the end of the year: three hundred available minus 230 sold. Under FIFO they are from the newer purchase layer, each with a $13 cost. Before the reporting-date impairment review, the remaining stock is recorded at 70 × $13 = $910.
Now the trader counts the end stock and discovers that ten of the seventy packs have damaged covers. Each damaged pack has a net realisable value of only $8 under the stipulated selling and completion cost conditions. The other sixty packs each have a net realisable value at least equal to their $13 cost.
The accounting principle is that inventory is measured at the lower of cost and net realisable value. For each undamaged pack, cost $13 is lower than or equal to its realisable value, so the retained carrying amount is $13. For each damaged pack, net realisable value $8 is lower than $13 cost, so it is recorded at $8.
Therefore sixty good packs contribute 60 × $13 = $780 to ending inventory, and ten damaged packs contribute 10 × $8 = $80. The properly valued ending Inventory is $860 rather than the unadjusted $910.
The reduction in inventory is $910 − $860 = $50. This is an impairment loss on inventory caused by the lower value of the ten damaged packs. The adjustment is not a disappearance of fifty physical units: the warehouse still contains seventy packs.
In a simplified journal illustration, debit Impairment Loss on Inventory $50 and credit Inventory $50. This reduces the carrying amount to $860 and recognises the impairment loss. Use the precise presentation required by the student’s school when preparing the full statements.
Gross profit on the 230 recorded sales before showing this separate impairment adjustment is Sales $4,370 less FIFO Cost of Sales $2,790, yielding $1,580. Showing the impairment loss separately below that subtotal, the trader must still recognise the $50 reduction in total profit.
Assume the trader also paid employee wages of $400 during the year, with another $120 of wages for work already performed still unpaid at year end. Thus Wages Expense is $400 + $120 = $520, and Wages Payable is a $120 current liability. The unpaid amount is not an additional bank transfer at the reporting date.
Utilities of $210 were consumed and paid during the year. No other income, expense, inventory insurance claim, tax, financing or adjustment is included. The teaching case is deliberately bounded so every number can be checked.
Using the separate impairment-loss presentation, the simplified profit is $1,580 gross profit − $50 inventory impairment − $520 wages expense − $210 utilities expense = $800. All amounts belong to the one stated financial year.
A second check uses total goods cost minus the correctly valued ending stock: $3,700 − $860 = $2,840 of total stock-related expense when the $50 impairment is included. That reconciles to $2,790 FIFO Cost of Sales plus $50 impairment. Revenue $4,370 less that combined $2,840 and other expenses of $730 also gives $800.
Do not silently call the $2,840 exactly the same ledger transaction as the $2,790 Cost of Sales recorded when customers purchased the goods. It is the combined stock-cost-and-impairment effect for this teaching reconciliation. The journal presentation distinguishes the event at sale from the later impairment adjustment.
What if the ten damaged packs had an estimated net realisable value of $10 each instead? The impairment would become ten × ($13 − $10) = $30, and ending inventory would be $780 + $100 = $880. Total profit would be $820 with all other original transactions unchanged.
What if none of the remaining stock had a net realisable value below its $13 cost? No impairment loss would arise, ending inventory would remain $910, and simplified profit would be $850 rather than the original $800.
Now change the sales volume while retaining the original initial purchase quantities. Suppose 240 packs are delivered at $19 each, and ten of the remaining sixty are damaged with $8 net realisable value. FIFO Cost of Sales becomes $1,100 for the first one hundred packs plus 140 × $13 = $1,820 for later units, totalling $2,920.
The remaining sixty units would cost 60 × $13 = $780 before impairment. Fifty undamaged packs at $13 and ten damaged packs at $8 give a valued closing stock of $650 + $80 = $730. The impairment loss remains $50.
Revenue at 240 sales is $4,560; gross profit before impairment is $4,560 − $2,920 = $1,640. After the $50 impairment, $520 wages and $210 utilities, profit becomes $860. This variant shows how the same valuation principle applies when the quantity sold changes.
Every student answer should preserve units, dates and categories. A correct closing stock figure of $860 is not eighty-six units or $860 of bank cash. It is the recognised value of seventy physical packs after a $50 reduction of recorded inventory cost.
| Original trading event | Working | Verified figure |
|---|---|---|
| Opening inventory | 100 units × $11 | $1,100 |
| Purchases on credit | 200 units × $13 | $2,600 |
| Available stock | 100 + 200 | 300 units |
| Available cost | 1,100 + 2,600 | $3,700 |
| Sales Revenue | 230 × $19 | $4,370 |
| FIFO first opening layer sold | 100 × $11 | $1,100 |
| FIFO newer layer sold | 130 × $13 | $1,690 |
| Cost of Sales at sale | 1,100 + 1,690 | $2,790 |
| Unadjusted ending units | 300 − 230 | 70 units |
| Unadjusted ending cost | 70 × $13 | $910 |
| Undamaged valued units | 60 × $13 | $780 |
| Damaged valued units | 10 × $8 | $80 |
| Ending inventory after impairment | 780 + 80 | $860 |
| Inventory impairment loss | 10 × (13 − 8) | $50 |
| Gross profit before separate impairment | 4,370 − 2,790 | $1,580 |
| Wages expense | 400 paid + 120 payable | $520 |
| Utilities expense | Given | $210 |
| Profit after inventory impairment | 1,580 − 50 − 520 − 210 | $800 |
An accurate final explanation can say: ‘The trader sold 230 packs with $2,790 FIFO cost of sales. Seventy packs remain, but ten are impaired, reducing ending inventory from $910 to $860. After the $50 impairment and other stated expenses, profit is $800.’
CHAPTER 3 OF 15
FIFO follows purchase layers, not the selling price
FIFO is an assumed inventory cost-flow method for the accounting records, not a licence to use whichever unit cost produces the most attractive profit. The case has two inventory layers: older stock costing $11 and newer stock costing $13.
Under FIFO, the one hundred older units are included in cost of sales before newer units. For 230 sales the newer contribution is 130 units, not the full 230. The resulting $2,790 should be reconstructible from the physical count.
A pupil might confuse the $19 selling price with the $13 newer purchase cost. Sales Revenue uses what the customer is charged; Cost of Sales uses the cost assigned to the goods leaving the business. They are connected in gross profit but answer different questions.
The remaining seventy stock units are allocated the newer $13 cost under the FIFO calculation. That is why the unadjusted ending amount is $910 before the valuation review.
A clear diagram can show a queue: one hundred older packs leave first, followed by 130 newer packs, leaving seventy in the later layer. The mathematical subtraction then makes sense instead of being an arbitrary rule.
A tutor should check whether the pupil can perform the same method with two new unit prices and a changed sale quantity. If the student keeps multiplying the full sale count by the most recent price, the FIFO principle has not yet been understood.
Real companies need proper purchase and stock records. A fictional exam-style problem supplies all the quantities needed for the calculation; it does not justify assuming what actual local traders do when their warehouse is not shown.
CHAPTER 4 OF 15
Lower of cost and net realisable value is an evidence rule
The ten damaged packs remain in the warehouse, but their expected realisable amount under the stated facts is only $8 each. Leaving them at $13 would overstate what the business can recover from those items.
Under the stipulated lower-of-cost-and-net-realisable-value approach, each damaged unit is measured at $8, giving a five-dollar reduction from cost. Across ten units the inventory impairment loss is $50.
The other sixty units have a realisable value at least equal to cost, so they remain valued at $13 each. A learner who writes all seventy units down to $8 has incorrectly applied the damaged-item condition to stock whose value has not fallen.
Prudence is relevant because the accounts should not overstate inventory merely to present a more favourable financial position. The adjustment relies on facts supplied in the fictional scenario, not a guess that every illustrated pack is unpopular.
Net realisable value is not necessarily the same as the original sticker price. The accounting concept concerns expected proceeds less appropriate costs to complete and sell, according to the specified syllabus treatment. Here the net amount of $8 has already been supplied, so the pupil should not subtract imaginary costs again.
A good tutor asks what evidence supports a write-down. Damaged condition and the stated lower realisable amount are sufficient for this exercise. If no decline were stated, inventing an impairment just to appear cautious would also be wrong.
The distinction between a valuation adjustment and stock disappearing is crucial. Seventy physical packs remain even after Inventory falls by $50 in monetary carrying amount.
CHAPTER 5 OF 15
Recording the sale and recording impairment happen at different times
When the 230 goods are sold on credit, the business records Trade Receivables $4,370 and Sales Revenue $4,370 under the stated assumptions. That recognises the customer’s obligation to pay for goods already delivered.
Under perpetual inventory recording, the corresponding cost of goods delivered is recognised at the time of sale. Debit Cost of Sales $2,790 and credit Inventory $2,790. This removes the appropriate FIFO cost from goods held.
Inventory initially had $1,100 opening plus $2,600 new purchases, so after the sale-cost entry it contains $3,700 − $2,790 = $910 in book cost. That is the pre-impairment balance, not a cash receipt.
The damaged-stock review happens at the reporting date. The inventory carrying amount requires a further $50 reduction. Debit Impairment Loss on Inventory $50 and credit Inventory $50 in the simplified journal illustration.
That second entry does not mean another fifty dollars was paid to a supplier or that the customers returned $50 of goods. It recognises a decline in value of stock the business still owns.
Later, if a customer settles a credit sale, Bank would increase and Trade Receivables decrease. The same sale revenue would not be recorded again. The original case does not specify such settlement amounts, so the teaching worksheet leaves the receivable uncollected.
Account names, chronology and amount bases should follow the course’s actual prescribed presentation. Correct debit and credit pairs are necessary but are not a substitute for explaining the business event.
CHAPTER 6 OF 15
Show the $50 impairment effect without double counting
The trader’s provisional gross profit from sales before the separate impairment adjustment is $1,580. That figure comes from $4,370 Sales Revenue less $2,790 FIFO Cost of Sales recognised as goods leave the business.
The damaged-stock check reveals a further $50 loss in value of goods still held. In the separate-line illustration, $50 impairment loss is recognised after that gross profit subtotal, along with Wages Expense $520 and Utilities Expense $210.
Profit becomes $1,580 − $50 − $520 − $210 = $800. The impairment does not create a second customer payment or change the number of units already sold.
A pupil may instead compute $3,700 goods available less the $860 adjusted closing inventory to obtain $2,840 as the total stock-cost-and-impairment effect. That combines the $2,790 recorded Cost of Sales and $50 impairment. It is a valid reconciliation of total expense effect, not a reason to post the same impairment twice.
Be precise with statement labels. The example separates the impairment loss from the original FIFO sale-cost entry; if a classroom presentation groups items differently, use the teacher’s appropriate prescribed format while retaining the same total profit effect.
Without recognising the inventory impairment, the original model’s profit would be $850 instead of $800. That $50 overstatement arises from valuing ten damaged packs at too high a figure.
Students should be able to articulate why correctly recognising a reduced asset value lowers reported results even though no new cash payment occurred at the instant of the adjustment.
CHAPTER 7 OF 15
Choose a weekday for the first broken FIFO or valuation step
A teenager may have no difficulty with arithmetic but still take 230 × $13 as Cost of Sales. A focused weekday tutorial should return to the opening one hundred goods at $11 and the newer two hundred at $13.
Use a queue diagram: sell all the older one hundred first, then 130 of the newer items. The pupil should independently reach $1,100 + $1,690 = $2,790.
Another student may determine Cost of Sales correctly but leave all remaining packs at $13 despite evidence that ten damaged packs have a lower net realisable value. The tutor should separate good stock from damaged stock and calculate the five-dollar reduction per damaged item.
A small changed test uses an $10 NRV for damaged packs. The impairment becomes ten × ($13 − $10) = $30, so closing inventory rises to $880 and profit to $820 when other facts remain unchanged.
Weekday support need not become an exhausting full mock examination. If the immediate gap is one incorrect valuation, a short corrected example and a delayed no-hints retest may be sufficient.
Families should include school dismissal, CCA, the actual journey to tutoring, dinner and homework before selecting a slot based solely on a convenient-looking hour.
Parents can ask the tutor whether the student subsequently explained the FIFO order and impairment basis independently, not just whether the calculation table was finished.
CHAPTER 8 OF 15
A weekend can connect quantity, cost, valuation and performance
A longer lesson may be appropriate when the pupil understands isolated journal entries but cannot relate all the stock movements to the end-of-year financial statements. Begin with a full physical tally from three hundred available to 230 sold and seventy remaining.
Have students compute the FIFO cost flow, then perform a separate valuation review. This avoids the common mistake of applying an impairment rate to goods no longer in inventory.
One student may calculate the Sales Revenue, another the FIFO Cost of Sales and a third the damaged-stock adjustment. Each should then complete the whole question independently after discussing the results.
Next build the provisional gross profit of $1,580 and identify the $50 inventory impairment separately. Adding wages and utilities produces the correctly adjusted $800 profit.
Introduce the 240-sales variant. The learner must remove a different number of newer items while still valuing ten damaged closing units at their $8 NRV. The answer should change for clear reasons rather than through a copied template.
Use the activity to explain why a good accountant needs both a stock record and an assessment of the condition of inventory. Counting units alone cannot reveal when recorded value needs adjustment.
A weekend session adds value when the teenager leaves able to explain the complete event on an unfamiliar question, not merely with another page of carefully copied entries.
CHAPTER 9 OF 15
Seven wrong inventory answers that imply different weaknesses
A wrong closing stock figure can result from a miscount, a FIFO error, ignoring damage or applying the damage assumption to every unit. The tutor must find the first mistake before prescribing practice.
| Student’s incorrect claim | What likely went wrong | Focused tutor response |
|---|---|---|
| 230 units cost $2,990 | All sold items costed at $13 | Use 100 at $11 and 130 at $13. |
| Ending stock contains 80 units | Physical count subtraction wrong | 300 available − 230 sold = 70. |
| All 70 units valued at $8 | Damaged condition applied universally | Only 10 impaired; 60 remain at $13. |
| Closing Inventory remains $910 | NRV impairment ignored | Record $50 reduction for 10 damaged packs. |
| $50 impairment is a cash payment | Valuation adjustment misread | No supplier bank transfer occurs at review. |
| $50 loss posted twice | Cost-and-impairment reconciliation confused | Separate sale cost from year-end write-down. |
| Only $400 wages are expensed | Wages payable omitted | Include $120 already incurred. |
A pupil who can describe the warehouse count but cannot calculate two unit costs needs numerical practice. Another who has perfect multiplication but invents a cash payment for impairment needs event classification.
Correcting a final figure without repairing the interpretation may lead to the same error when the next question uses damaged merchandise, different purchase dates or a different NRV.
Parents should look for a new no-hints response after the explanation and for the student to name the affected accounts correctly.
A quality tutorial does not treat all wrong answers as evidence that the child must simply do more timed past-year questions.
CHAPTER 10 OF 15
Ten original G3 inventory tasks and their checked answers
These new examples are learning checks, not reproduced official SEC examination questions. Students should explain both the physical count and money valuation.
1. Opening 100 packs at $11 plus 200 purchases at $13 equals 300 units with $3,700 total recorded cost.
2. Sales of 230 at $19 generate $4,370 Sales Revenue.
3. FIFO Cost of Sales is 100 × $11 + 130 × $13 = $2,790.
4. Seventy remaining units at $13 cost have an unadjusted inventory amount of $910.
5. Ten damaged units with $8 NRV instead of $13 cost produce impairment of 10 × $5 = $50.
6. Properly valued closing Inventory is sixty × $13 plus ten × $8, totalling $860.
7. Gross profit before separate inventory impairment is $4,370 − $2,790 = $1,580.
8. Wages $400 paid plus $120 owed give $520 expense. After impairment $50 and utilities $210, profit is $800.
9. If damaged NRV rises to $10 under otherwise identical facts, impairment is $30, ending stock $880 and profit $820.
10. If 240 goods are sold with ten of the sixty remaining damaged at $8 NRV, FIFO Cost of Sales is $2,920, ending stock $730 and profit $860 after the same impairment and other expenses.
The child should explain why the sold unit count is not equal to the remaining stock and why changing the NRV does not mean a new customer has arrived.
After two days, use a completely new two-price inventory question to test whether FIFO and the lower-of-cost-and-NRV rule remain available without hints.
CHAPTER 11 OF 15
Align the teaching to the official G3 K342 scope
The 2027 G3 K342 syllabus explicitly requires FIFO calculation of Cost of Sales and ending inventory, use of perpetual inventory records and application of the lower of cost and net realisable value for closing stock.
It also includes accounting for inventory impairment loss and, where relevant, adjustment for insurance claims. The present case supplies no insurance claim, so the student should not invent one.
The G3 syllabus limits the stated examination context for effects of inventory overstatement or understatement to one financial period. This example uses one reporting year and does not attempt an unsupported long multi-year correction.
G2 K233 is another official 2027 POA course with a separate scope. Parents should use the pupil’s actual registered level and the teacher’s teaching sequence rather than assuming every mixed G3 case fits a G2 class.
An exact account label may depend on whether the school is using a ledger or statement presentation. The necessary business relationship remains constant: sold units leave inventory at the correct FIFO cost and damaged closing units are written down when NRV is lower.
Financial reporting carries an ethical obligation not to overstate assets simply because a higher number looks reassuring. A realistic impairment is supported by evidence, not by a vague desire to be conservative.
No Aljunied trader’s records are being disclosed. The product, sales, damage and price figures are invented for a transparent teaching example.
CHAPTER 12 OF 15
What personalised feedback means in a three-student POA group
The Clementi Mathematics tuition reference illustrates eduKate’s premium three-student method: first principles, close attention and a tutor who can identify a learner’s exact misconception instead of merely assigning repetitive worksheets.
In this inventory case one student may multiply all units by the newest cost, another may overlook the damaged goods and a third may correct inventory value but fail to recognise the effect on profit.
Each needs a different intervention. The first benefits from a two-layer inventory diagram, the second from an item-level cost-versus-NRV table and the third from an adjusted profit bridge.
Peer explanation can help learners understand that the physical units remaining and the monetary value reported are different measurements. But every pupil must finish with an altered scenario completed independently.
Parents should ask for the original wrong step, a relevant correction and a delayed no-hints answer. Small class size alone cannot guarantee examination results.
The Clementi article describes the teaching approach, not a confirmed specialist POA tutor in Aljunied. The actual offered level, class venue, timetable and fees require a separate enquiry.
An effective lesson supports the student’s real school progress and independent confidence, not the idea that every pupil needs more hours indefinitely.
CHAPTER 13 OF 15
Aljunied as a verified place, not a fictional business address
HDB’s Geylang Town Design Guide identifies Aljunied Road, Sims Drive and Sims Avenue as elements of the broader neighbourhood and transport network. Aljunied Avenue 2’s Geylang East neighbourhood centre is documented separately by HDB.
Those sources help a parent understand the locality. They do not support claiming that the invented illustrated-pack trader operates from Aljunied MRT, a housing block or a nearby commercial property.
A family living near Sims Drive may have a different route from someone nearer Geylang East or the Aljunied Road corridor. A location keyword in an article cannot determine actual tuition travel time.
Compare the child’s school dismissal, CCA, transport, the confirmed tutor address, the trip home, dinner and the next day’s workload before booking a class.
One targeted weekday session can be useful if an isolated FIFO mistake is still fresh. A longer weekend may help with full reporting-date valuation when the student needs more time and remains rested.
Neighbouring Geylang, MacPherson and Woodleigh educational guides provide other reading routes without implying a staffed centre in every named estate.
Parents should verify actual educator, subject level, physical venue, fees and available session times rather than inferring service provision from a geographic title.
CHAPTER 14 OF 15
Two weeks to test whether the inventory concepts truly hold
Begin by handing the pupil the opening stock, purchase and sales quantities without the complete solution. Ask them to build the physical inventory movement and explain the FIFO order aloud.
Keep the first attempt and diagnose the first error. If the student chooses the wrong purchase layer, teach the sequence before discussing the year-end valuation.
Once $2,790 Cost of Sales and seventy remaining units are secure, introduce the ten damaged items. The learner should calculate lower-of-cost-and-NRV by separating damaged from undamaged units.
Two days later, change the damaged NRV to $10 and ask the teenager to rebuild ending Inventory, impairment and profit independently.
In week two, change the sales count to 240. The pupil should correctly update FIFO Cost of Sales, closing count, damaged-item adjustment and period profit without looking at the original table.
Use an unfamiliar product and altered purchase prices for a final no-hints check. A student who can explain each account from the business event has progressed beyond memorisation.
Choose continuing weekday or weekend tuition only if the evidence shows a remaining gap that actually needs instruction. A larger number of practice papers is not the learning objective.
CHAPTER 15 OF 15
Questions Aljunied parents ask about G3 inventory accounting
Is FIFO in the 2027 G3 K342 syllabus? Yes. The syllabus requires FIFO calculation for cost of sales and ending inventory.
Why is the Cost of Sales $2,790? FIFO allocates the first 100 older packs at $11 and the next 130 at $13 to the 230 sold items.
Why does ending Inventory fall from $910 to $860? Ten damaged packs have a supplied NRV of $8, which is $5 below their $13 cost, giving a $50 impairment.
Did fifty physical packs disappear? No. Seventy packs still exist; the $50 is a monetary write-down, not a unit count.
What is the case’s corrected profit? $800, after $1,580 gross profit before separate impairment, $50 impairment, $520 wages and $210 utilities.
Does the impairment require an additional bank payment? Not under this example. It adjusts carrying value and recognised loss, not cash at the moment of valuation.
Would weekday or weekend tuition help more? Choose a short weekday for one FIFO or NRV gap and weekend time for connected reporting if the student can learn productively.
Is this an actual Aljunied shop or confirmed local POA class? No. The business is fictional, and tutoring availability requires direct verification.

Final thought: A good inventory answer accounts for goods that have actually left the warehouse and the honest value of what remains. Correct arithmetic matters, but truthful representation is the heart of POA.
