SOLUTION
| Sales | 4,00,000 |
| Gross Profit | 1,00,000 |
| Cost of Goods Sold | Sales − Gross Profit = 4,00,000 − 1,00,000 = 3,00,000 |
| Let Opening Inventory | x |
| Closing Inventory | x + 40,000 |
| 1,20,000 | x + 40,000 |
| X | 80,000 |
| Opening Inventory | 80,000 |
Average Inventory =(Opening Inventory + Closing Inventory ) / 2
= (80000 +120000) / 2
= 100000
Inventory Turnover Ratio = Cost of Goods Sold / Average Inventory
= 300000 / 100000
= 3
