A company has inventory data as follows: Opening stock = 200 units @ ₹40; Purchases = 400 units @ ₹50. Units sold = 300. Using the Weighted Average Cost method, what is the value of closing inventory (300 units)? 

Total cost of goods available = (200 × ₹40) + (400 × ₹50) = ₹8,000 + ₹20,000 = ₹28,000. Total units available = 200 + 400 = 600 units. Weighted Average Cost per unit = ₹28,000 ÷ 600 = ₹46.67 per unit (approximately). Closing inventory = 600 − 300 = 300 units. Value = 300 × ₹28,000/600 = ₹28,000 × 0.5 = ₹14,000. This can also be computed as: closing inventory is exactly half of total available units, so closing inventory value = half of total cost = ₹28,000 ÷ 2 = ₹14,000. The figures are deliberately kept clean so the answer can be arrived at mentally without a calculator.
