If one-third of one-fourth of a number is 15, then three-tenth of that number is :


A) 35

B) 36

C) 45

D) 54

E) 59

Answer:

Option D

Explanation:

Let the number be $x$.
Then, $\frac{1}{3}$ of $\frac{1}{4}$ of $x=15$
$\Leftrightarrow x = 15 \times 12=180$.
So, required number $=\left(\frac{3}{10} \times 180\right)=54$.
