Answer:
a. Inventory Turnover:
= Cost of goods sold / Average inventory for the year
= 642,400 / 210,000
= 3.06
b. Number of days' sales in inventory
= Ending inventory / (COGS / 365)
= 156,409 / (642,400 / 365)
= 88.9 days
c. Accounts receivable turnover
= Net sales / Average Accounts Receivable
= 1,022,000 / 43,000
= 23.77 times
d. Number of days sales in accounts receivable
= Accounts Receivable at year end / (Net sales / 365)
= 22,400 / (1,022,000 / 365)
= 8 days
