Therefore, under FIFO
A) cost of goods sold = 575
B) Ending inventory = 725
C) Gross profit = (25 × 30) - 575 = 1250 - 575 = 675
2) computation of Ending inventory ,COGS and Gross profit under
LIFO method :

Therefore, under LIFO
A) cost of goods sold = 725
B) Ending inventory = 575
C) Gross profit = (25 × 30) - 725 = 1250 - 725 = 525
