Working: $12,000 + ($ 85,000 - $3,000) +$ 1,500 - $15,000 =$ 79,500. (3m) Answer: $79,500
Working: Average Inventory = ( $30,000 +$ 50,000) / 2 = $40,000. Turnover =$ 240,000 / $40,000 = 6. (2m) Answer: 6 times
Working: $42,000 =$ 5,000 + Purchases - $8,000. Purchases =$ 42,000 + $8,000 -$ 5,000 = $45,000. (3m) Answer:$ 45,000
Working: 100 units @ $14 (latest) + 50 units @$ 12 (next latest). $1,400 +$ 600 = $2,000. (3m) Answer:$ 2,000
Working: Average cost per unit = $15,000 / 1,000 =$ 15. Closing inventory = 200 units * $15 =$ 3,000. (2m) Answer: $3,000

Closing inventory overstated $\rightarrow$ Cost of Sales understated $\rightarrow$ Profit is overstated by $1,500. (2m)
Company A is more efficient. (1m) A higher turnover rate indicates that stock is sold and replaced more quickly (1m), reducing holding costs (1m) and the risk of obsolescence (1m).
(Any two of the following):
- Decrease in market demand for products. (2m)
- Overstocking/Poor purchasing decisions. (2m)
- Increased competition leading to slower sales. (2m)
- Change in product mix to items with longer lead times. (2m)
FIFO. (1m) Perishable goods must be sold in the order they are received to avoid spoilage (1m). FIFO assumes the oldest stock is sold first, which mirrors the actual physical movement of fresh produce. (2m)
A low inventory turnover rate means capital is tied up in unsold stock (2m). This reduces the amount of cash available for other current liabilities, thereby worsening the company's liquidity/current ratio. (2m)
