Explanation / Answer

Ans.1 Number of units available for sale 800 Cost of goods available for sale 73600 *Calculation: Date Particulars Units Rate Cost 1-Jan Beginning inventory 240 80 19200 15-Jan Purchase 360 90 32400 24-Jan Purchase 200 110 22000 Total 800 73600 Ans.2 Number of units in ending inventory 490 *Calculation: Total units available for sale - Units sold 800 - 310 490 Ans.3 FIFO LIFO Weighted Average Cost of goods sold 25500 31900 28520 Cost of Ending inventory 48100 41700 45080 *FIFO Date Units Rate COGS Date Units Rate Ending inventory 1-Jan 240 80 19200 24-Jan 200 110 22000 15-Jan 70 90 6300 15-Jan 290 90 26100 310 25500 490 48100 *LIFO: Date Units Rate COGS Date Units Rate Ending inventory 24-Jan 200 110 22000 1-Jan 240 80 19200 15-Jan 110 90 9900 15-Jan 250 90 22500 310 31900 490 41700 *Weighted Average: Weighted average cost per unit = Cost of goods available for sale / Number of units available for sale 73600 / 800 92 Cost of goods sold = Weighted average unit cost * Units sold 92 * 310 28520 Cost of Ending inventory = Weighted Average cost per unit * Ending inventory units 92 * 490 45080
