Question

If the CP of 15 articles equals to the SP of 12 articles, find the gain percent.

gain percent = 25%

Step-by-step explanation:

To solve the question given, we will follow the steps below:

gain%  =    ×    100%

But from the question;

"CP of 15 articles equals to the SP of 12 articles", this implies that

15 c.p  =  12 s.p

s.p = 15c.p  /   12

s.p  =       =  

s.p  =  

substitute  s.p  =     into the formula

gain%  =    ×    100%

      =     ×    100%

       =        ×    100%

  =     ÷   c.p      ×    100%

=     ×      ×    100%

=    ×    100%

=  25 %
