Principles of Accounts Secondary 4 — Inventory Costing: Answer Key

Total Marks: 60

Section A Answers (12 marks)

Q1 (1 mark): Prudence concept (or conservatism).
Teaching note: Inventory must not be overstated; prudence means recognizing losses early.

Q2 (2 marks): Net realisable value = estimated selling price minus estimated costs to complete and sell.
Marking: 1 mark definition of selling price less cost; 1 mark mention of costs to sell.

Q3 (2 marks):
COGS = 8,400 + (52,000 − 2,000) + 1,200 − 9,100 = $50,500
Working: Open 8,400 + Net Pur 50,000 + Carriage 1,200 = 59,600 − Close 9,100.
Common mistake: adding purchases returns instead of deducting.

Q4 (1 mark): Profit is overstated by $3,000.
Reason: Overstated closing inventory reduces COGS, increasing profit.

Q5 (2 marks): Inventory is owned, expected to be sold within 12 months → current asset.
Marking: 1 mark ownership/expected sale; 1 mark current (within year).

Q6 (2 marks): FIFO: remaining 100 units from 10 Mar @ $6 =$ 600.
Working: Sold 150 (100@5,[email protected]), sold 200 ([email protected],50@6). Left: 100@6.

Section B Answers (16 marks)

Q7 (3 marks):
After 15 Jan avg = (500+1100)/300= $5.333. After sale 150 left [email protected]. 10 Mar avg = (800+900)/250=$ 6.80. After sale 200 left [email protected].
Closing: [email protected] +150@6 = $340+$ 900=$1,240.
Marking: 1 each for averages and final.

Q8 (2 marks): FIFO gives higher closing inventory and lower COGS in rising prices. AVCO smooths cost.

Q9 (3 marks): COGS: 50@10 +70@12 = 500+840= $1,340. Closing 110 (30@12+80@14)=$ 1,640.
Marking: 1 method, 2 answer.

Q10 (3 marks): Avg1=(800+1320)/500= $4.24. After sale [email protected] left 250. Avg2=(1060+460)/350=$ 4.457. 350×4.457=$1,560.
Marking: steps 2, final 1.

Q11 (1 mark): Matches physical flow / simpler.

Q12 (2 marks): FIFO uses older lower costs → lower COGS → higher gross profit when prices rise.

Section C Answers (16 marks)

Q13 (2 marks): Avg Inv = (18+22)/2=20k. Turnover=120/20=6 times.

Q14 (3 marks): A turns faster → more efficient, lower holding cost. B slower → possible overstock. Context needed.
Marking: compare 1, efficiency 1, caution 1.

Q15 (3 marks): Avg inv = (10+12+15+14+16)/5? Use year avg = (10+16)/2=13k or qtr avg 13k. Turnover = total COGS 184k /13k =14.15.
From table: COGS sum=38+42+51+53=184. Avg=(10+16)/2=13.
Marking: avg 1, turnover 2.

Q16 (2 marks): Understated closing inv → higher COGS → lower avg inv → turnover overstated (too high).

Q17 (3 marks): Good: liquid, less obsolescence. Bad: stockouts, lost sales.
Marking: each point 1.5.

Section D Answers (16 marks)

Q18 (4 marks): COGS=20+140−30=130k. GP=200−130=70k. Avg inv=25k. Turn=200? COGS/avg=130/25=5.2.
Marking: COGS1 GP1 Turn2.

Q19 (4 marks): COGS = 160×75% =120k. Closing =15+90−120=−15 → est 0 (or loss). Actually 15+90=105; 105−120=−15 impossible → fire loss 15k. Closing est $0.
Marking: margin1 COGS1 calc1 ans1.

Q20 (4 marks): Cost 1000 NRV 600 → value at 600. Loss 400 recognized. Prevents overstating asset/profit.
Marking: basis1 amount1 effect1 explain1.
