Question

One-third of one fourth of a number is $12$. Then the number is?

• A. $96$
• B. $144$
• C. $108$
• D. $36$

Answer 1

The correct option is B $144$

Let the number be $x$.

We know that the term "of" indicates the sign of multiplication.

Now, it is given that one third of one fourth of $x$ is $12$, therefore, we have:

$\frac{1}{3}\times \frac{1}{4}\times x=12\Rightarrow \frac{x}{12}=12\Rightarrow x=12\times 12\Rightarrow x=144$

Hence, the number is $144$.
