Given:
Selling price of 9 articles is equal to the cost price of 15 articles.
Formula Used:
Profit Percentage=(CS−C)×100
Solution:
Selling price of 9 articles is equal to the cost price of 15 articles.
So, the equation is:
9S=15C
so cost price = 9 unit
selling price = 15 unit
Profit Percentage=(CS−C)×100
(135−1)×100=(35−3)×100=32×100=66.67%
