Question

What percent of 20 is 30?

Answer 1

Let $x\%$ of $20$ be $30$.

In math, 'of' means multiply.

Hence, on replacing 'of' with multiply, we get:

$\Rightarrow \frac{x}{100}\times 20=30$

$\Rightarrow x=\frac{30}{20}\times 100$

$\Rightarrow x=\frac{3}{2}\times 100$

$=150\%$

Hence, $30$ is $150\%$ of $20$.
