Calculation of Pure Gold Received by the Babylonian King

To calculate the amount of pure gold received by the Babylonian king, we can use the information provided in the letter. The letter states that when 20 minas of gold were put into the furnace, only 5 minas of pure gold were obtained.

1 mina is equal to 489.6 grams. Therefore, to find the amount of pure gold obtained, we can use the following calculation:

Amount of Pure Gold = (5 minas) x (489.6 grams/mina)

Let's calculate the amount of pure gold received by the Babylonian king.

Calculation:

Amount of Pure Gold = 5 minas x 489.6 grams/mina = 2448 grams

So, the Babylonian king received 2448 grams of pure gold.

Percentage of Pure Gold in the Gift

To find the percentage of pure gold in the gift, we can use the following calculation:

Percentage of Pure Gold = (Amount of Pure Gold / Total Gold) x 100%

Given that 20 minas of gold were put into the furnace, and only 5 minas of pure gold were obtained, we can calculate the percentage of pure gold in the gift.

Calculation:

Percentage of Pure Gold = (2448 grams / (20 minas x 489.6 grams/mina)) x 100% Percentage of Pure Gold = (2448 grams / 9792 grams) x 100% Percentage of Pure Gold ≈ 25%

Therefore, the percentage of pure gold in the gift was approximately 25%.

So, the Babylonian king received 2448 grams of pure gold, and the gift contained approximately 25% pure gold.
