By selling an article, a man makes a profit of 25% of its selling price. His profit per cent is:
[A]16\frac{2}{3}\%
[B]20
[C]33\frac{1}{3}\%
[D]25

\mathbf{33\frac{1}{3}\%}
If the SP of article be x,
then its CP = x - \frac{x}{4} = \frac{3x}{4}Rs.
\therefore Gain \% = \frac{\frac{x}{4}}{\frac{3x}{4}}\times 100
= \frac{100}{3} = 33\frac{1}{3}\%
Hence option [C] is the right answer.
