Question

If the cost price of 15 articles is equal to the selling price of 20 articles, then find the loss% in the transaction.

• A. 16%
• B. 20%
• C. 25%
• D. 26%
• E. None of these

Answer 1

The correct option is C 25%

$15\times CP=20\times SP$
$\Rightarrow \frac{SP}{CP}=\frac{15}{20}$
$\frac{SP}{CP}-1=\frac{15}{20}-1$
$\Rightarrow \frac{SP-CP}{CP}=\frac{15-20}{20}$
$=Loss=\frac{5}{20}$
Loss percentage $=\frac{5}{20}\times 100=25\%$
