SOLUTION
Average Inventory = 30,000 + 90,0002
= Rs. 60,000
Opening Inventory = 3,00,000 × 10%
= Rs. 30,000
Closing Inventory = 30,000 × 3
= Rs. 90,000
Cost of Revenue from Operations = Revenue from Operations – Gross Profit
= 4,00,000 – 1,00,000
= Rs. 3,00,000
Inventory Turnover Ratio = Cost of Revenue from Operations / Average Inventory
= 3,00,000 / 60,000
= 5 Times
