Question

Even after offering a 15 % discount on his customers, a trader is still earning a 19% profit .By how much percentage has the trader marked up his cost price?

Answer 1

original mark up price = n

cost price = 100

new mark up price after offering 15% discount is 119

 

119 / n = (100-15)/ 100

 

119 / n = 85 / 100

 

n= 140

 

 original mark up price is 140

so trader marked up his cost price by 40%
