Question

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

• A. $75$
• B. $22$
• C. $54$
• D. $66$

Answer 1

Answer: (C)

$54$

Let the required number be $x$

Then According to question,

$\frac{1}{3}\left(\frac{x}{4}\right)=15$

$⟹x=15\times 12=180$

So , $\frac{3}{10}x=\frac{3}{10}\left(180\right)=54$
