Question

A gold ring is 58.33% pure, its purity can be alternatively shown as ________ .

• A. 24 carat
• B. 22 carat
• C. 14 carat
• D. 18 carat

Hint:

To convert gold purity to carats, multiply the percentage purity by 24 and divide by 100.

Answer 1

The Correct Option is C

The purity of gold is often measured in carats, where 24 carat is considered pure gold.
To convert the percentage purity to carats, use the following relationship: \[ \text{Purity in carats} = \left( \frac{\text{Purity percentage}}{100} \right) \times 24 \] Given that the purity is 58.33%, we calculate the carat equivalent as: \[ \left( \frac{58.33}{100} \right) \times 24 = 14 \, \text{carat} \]
Thus, the gold ring's purity can be alternatively shown as 14 carat.

Thus, the correct answer is option (3).

Answer 2

A gold ring that is 58.33% pure gold can alternatively be expressed as 14 carat gold.

Understanding Purity and Carat:
The purity of gold is often measured in carats, where 24 carats represent pure gold (100%).
The carat value indicates how many parts out of 24 are pure gold in the alloy.

Calculation:
Purity percentage = (Carat value / 24) × 100
Given the purity is 58.33%, we can calculate the carat value:
Carat value = (58.33 / 100) × 24 = 14 carats

Significance:
- 14 carat gold means that 14 parts out of 24 are pure gold, and the rest is made up of other metals.
- This is a common standard for gold jewelry, offering a balance between purity and durability.

Summary:
- 58.33% purity corresponds to 14 carat gold.
- 24 carats is pure gold.
- Carat value is a measure of gold purity based on a 24-part system.

This standard helps buyers understand the quality and value of gold jewelry.
