Question

A trader marks his good 40percent above cp and allows discount of 25percent what is his profit percent?

Answer 1

Let original CP = Rs. 100.
Then, the Marked Price = 40% of 100 + 100 = 140.
SP = 140 - 25% of 140 = 105.
%Profit = (5*100)/100 = 5%.

Net Graphic Change Method:

100 == 40% UP ==> 140 == 25% discount ==> 105. So, % Profit = 5%.

please mark me as brain list

Answer 2

CP percent according to mark = 40 %
CP percent according to shopkeeper= (40-25)%
15 %

Real CP percent profit of shopkeeper = 15%
