Q:

# The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:

 A) 15 B) 16 C) 18 D) 25

${\color{Black}&space;\therefore&space;\left&space;(&space;\frac{20-x}{x}\times&space;100=25&space;\right&space;)}$

$\inline \fn_jvn \Rightarrow$2000 - 100x = 25x

$\inline \fn_jvn \Rightarrow$125x=2000

$\inline \fn_jvn \Rightarrow$x=16
