Question

The CP of $20$ articles is the same as the SP of $x$ articles. If the profit is $25\%$, the value of $x$ is

• A. $15$
• B. $16$
• C. $18$
• D. $25$

Answer 1

The correct option is B $16$

CP of 20 articles is the SP of x articles.
If the CP of 1 article is 1, then the SP of x articles will be 20.
Profit percent $=25$
Therefore, if SP is 125, then CP is 100.
If 20 is SP, then CP is $\frac{100}{125}\times 40=16$
Number of articles, $x=16$
