Question

If $45\%$ of $90=x\%$ of $81$, then the value of $x$ is

• A. $405$
• B. $500$
• C. $50$
• D. $28.5$

Answer 1

The correct option is C $50$

Given, $45\%$ of $90=x\%$ of $81$
$\Rightarrow \frac{45}{100}\times 90=\frac{x}{100}\times 81$
$\Rightarrow x=\frac{45\times 90}{81}=50$

Thus, $x$ is equal to $50$.
