$\large ❀ \bf\red {\underline{information}}❀$

The above Question is provided from

• Class 7
• Chapter - 10
• Chapter Name - Percentage

$\large ❀ \bf\red {\underline{Solution}}❀$

• Let x kg be the amount of the required ore.

$\large\bf \red {12\%\:of \: x \: kg \: = 69 \: kg} \\ \\ \\ \large \red\implies\bf \green{( \frac{12}{100 \times x})kg = 69 \: kg} \\ \\ \\ \large \red\implies \bf \green{x = ( \frac{69 \times 100}{12})kg \: = \: 575 \: kg }$

• Hence, 575 kg of ore is required to get 69 kg of copper.
