The relative amount of gold in an alloy is commonly expressed in units of carats. Pure gold is 24 carats, and the percentage of gold in an alloy is given as a percentage of this value. For example, an alloy that is 50 percent gold is 12 carats. State the purity of the gold jewelry in carats.

Answer 1

This makes no sense. What gold jewelry? 50% is 12 carats if that is the question but that's also the answer.
