SOLUTION
Inventory Turnover Ratio = Cost of Goods sold / Average Inventory
8 = 3,00,000 / Average Inventory
Average Inventory = Rs. 37,500
Let Closing Inventory = x
Opening Inventory = 2x + x
= 3x
Average Inventory = Opening Inventory + Closing Inventory / 2
37,500 = 3X +X / 2
or, 4x = 75,000
X = 18,750
Closing Inventory = x = Rs 18,750
Opening Inventory = 3x
= 3 × 18,750
= Rs 56,250
