135
236
345
454

Answer:- 1

Explanation:-

Solution:

\begin{aligned} Let the number be x \\ Then, \frac{1}{3} of \frac{1}{4} of x = 15 \Leftrightarrow x = 15 \times 15 = 180 \\ So, required number \\ = (\frac{3}{10} \times 180) = 54 \end{aligned}

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