Question: how to calculate gold rate percentage?
Answer: To get the gram price, divide $400 by 31. (1 troy ounce equals approximately 31 gm).
Thus, $400/31 = approximately $13 per gm.
To get the pure gold price for the item, multiply 3 gm times $13.
Thus, 3 x $13 = $39.
To get the 14K gold price for the item multiply $39 by 0.6.
Thus, $39 x 0.6 = $23.40.
