HUMAN NUTRITION

Detailed explanation-1: -FIFO (“First-In, First-Out”) assumes that the oldest products in a company’s inventory have been sold first and goes by those production costs. The LIFO (“Last-In, First-Out”) method assumes that the most recent products in a company’s inventory have been sold first and uses those costs instead.

Detailed explanation-2: -First in, first out (FIFO) is an inventory method that assumes the first goods purchased are the first goods sold. This means that older inventory will get shipped out before newer inventory and the prices or values of each piece of inventory represents the most accurate estimation.
