give me right answer please with copy solution​

Answer 1

Given that:

• An ornament is made of gold and copper and weights 52.
• 2/13 of its part is copper.

To Find:

• The weight of pure gold in it?

Let us assume:

• The weight of pure gold be x.

According to the question.

Gold + Copper = Ornament

ㅤ↠ㅤx + 2/13 of 52 = 52

ㅤ↠ㅤx + (2 × 52)/13 = 52

ㅤ↠ㅤx + (2 × 4) = 52

ㅤ↠ㅤx + 8 = 52

ㅤ↠ㅤx = 52 - 8

ㅤ↠ㅤx = 44

Hence,

• The weight of pure gold is 44 kg.
