If the cost price of $20$ articles is equal to the selling price of $15$ articles, find the profit percent?

A

$33 \frac{1}{2}$

B

$33 \frac{1}{3}$

C

$33 \frac{1}{5}$

D

$33 \frac{1}{7}$

Solution

$CP$ of $20$ articles $=$ $SP$ of $15$ articles

$\Rightarrow \quad \frac{\text { CP of } 1 \text { article }}{\text { SP of } 1 \text { article }}=\frac{15}{20}=\frac{3}{4}$

Profit\% $=\frac{4-3}{3} \times 100=33.33 \%$
