In using LIFO, each item sold is from the last inventory received while the FIFO is of the opinion that item sold is the oldest stock of inventory.

Under LIFO, cost of ending merchandise is as follows:

10 units (20-10) at      $20=$200

10 units (30-20) at     $25=$250

10 units at  $30                =$300

Under FIFO, cost of ending inventory is as follows:

20 units at  $25                 =$500

10 units at $30                   = $300

total value of inventory      =$800

The correct option is A,$800
