Answer 2

$\huge\underline{Answer}$

• let the number = x
• 18 percent of x = 18/100 × x

According to question:

$⟹\large \: x - \frac{18}{100} x = 410$

$⟹\large \: x(1 - \frac{18}{100} ) = 410$

$⟹\large{ \: x( \frac{82}{100} )} = 410$

$⟹\large \: x = 410 \div \frac{82}{100}$

$⟹\large \: x = 410 \times \frac{100}{82}$

$⟹x = 5 \times 100$

$⟹x = 500$

500 is the number
