Answer 1

Given:-

• An alloy of tin and copper consists of 15 parts of tin and 105 parts copper.

To find:-

• The percentage of copper in the alloy.

Solution:-

Here,

• Tin = 15 parts
• Copper = 105 parts

According to the question,

★ Alloy of tin and copper:-

→ (15 + 105)

→ 120

Now,

• Finding the Percentage of copper in alloy.

→ 105/120 × 100%

→ 87.5%

Hence,

• Percentage of copper is 87.5 % in alloy.
