Question

If $6\frac{1}{4}\%$ of a weight is $0.25kg$. What is $45\%$ of this weight?

Answer 1

Let $xkg$ be the weight.

Therefore,ATQ,

$\Rightarrow 6\frac{1}{4}\%\times x=0.25$

$\Rightarrow \frac{25}{4}\%\times x=0.25$

$\Rightarrow \frac{25}{4\times 100}\times x=0.25$

$\Rightarrow \frac{0.25}{4}\times x=0.25$

$\Rightarrow x=\frac{0.25\times 4}{0.25}$

$\Rightarrow x=4kg$

So, $45\%$ of $x$ is,

$\Rightarrow \frac{45}{100}\times x=\frac{45}{100}\times 4$

$\Rightarrow x=1.8kg$
