First-In-First Out (FIFO): This means the stock sold will be assumed to be the stock first put into the warehouse. Therefore, it implies that the stock remains at the warehouse will be the level last ordered and will employ the : most current value.

ii. Last-in-First-dut (LIFO)

It is the reverse thinking of FIFO. It states that the stock remains at the warehouse will be the stack first ordered.

Remark:

(1) The integral. part and decimal part. can be done separately.

(2) It can be easily understood by

the following

11i. Average. Cost

It points out that the value of the- remaining should be calculated according to the average price of the stock.

Example:- (Samé "data: 'ast the previous-example:)

The average cost'is: -- (100x30)+(100x40)+(100x45)+(100×50) 400
