Given that:

• Ritu purchases an ornament of gold and copper which weights 34 kg.
• 3/17 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 + 3/17 of 34 = 34

ㅤ↠ㅤx + (3 × 34)/17 = 34

ㅤ↠ㅤx + (3 × 2) = 34

ㅤ↠ㅤx + 6 = 34

ㅤ↠ㅤx = 34 - 6

ㅤ↠ㅤx = 28

Hence,

• The weight of pure gold is 28 kg.

Answer:

28

Step-by-step explanation:

14/17 parts of it is gold
