Answer:

It means it contains 22K and 18K pure gold respectively. The rest is some form of impurity (mainly copper or silver).

Explanation:

1K=200 mg. It is used to find the purity of precious metals or gemstones. The carat is divisible into 100 points of 2 mg. It considers the metal as total of 24 parts and represents the quality of gold as number of parts of gold from a total of 24 parts. 24 karat gold means pure gold, which means 24 of 24 parts of the alloy is gold, making it pure gold.
