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.
