Question

Purity of gold is 15 carat. What is the percentage of gold in the ornaments?​

Answer 1

Answer:

The percentage of gold used in the ornaments is 62.50%.

Explanation:

As per the international conventions,

24-carat gold is the purest quality of gold, i.e., 24-carat gold is 100% pure.

∴ 1-carat gold is = $\frac{100}{24}$% pure

∴ 15-carat gold is = ($\frac{100}{24}$ × 15)% pure = 62.50% pure

This amount of gold is purely present in the 15-carat quality of gold, which means that if any jewellery is made from this 15-carat gold, the same jewellery will have 62.50% of gold in it.
