Answer 1

Answer:

Profit% = 18.1818%

Step-by-step explanation:

Let the Cost Price (CP) of 1articles will be x.

CP of 13 articles = 13x

SP of 11 articles = 13x

SP of 1 articles = 13x/11

Profit = SP - CP

= 13x/11 - x

= (13x - 11x)/11

= 2x/11

Profit% = P×100/CP

= 2x/11 × 100/x

= 200x/11x

= 200/11

= 18.1818%
