$5 \%$ of which number is $12$?
A
$120$
B
$180$

$240$
D
$320$

Answer
Correct option: C.
$240$
Let the required number be $x$.
Then, we have:
$(5 \%$ of $x) = 12$
$\Rightarrow\Big(\text{x}\times\frac{5}{100}\Big)=12$
$\Rightarrow\frac{5\text{x}}{100}=12$
$\Rightarrow\text{x}=\Big(12\times\frac{100}{5}\Big)$
$\Rightarrow\text{x}=240$
