Question:
A soldering material is made up of copper and tin. If the material consists of 72% copper, then what will be the ratio of copper and tin in the material?
A soldering material is made up of copper and tin. If the material consists of 72% copper, then what will be the ratio of copper and tin in the material?
Show Hint
To calculate the ratio, divide the percentage of copper by the percentage of tin, then simplify the fraction.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
If the material consists of 72% copper, the remaining 28% will be tin. The ratio of copper to tin is thus \( \frac{72}{28} = \frac{18}{7} \).
