Question from karonn, a student:

Kinky Trading sells an items for RM90 less 25% and 10%. Softee Trading sells the same item for RM100 less 30%.

(a) find the net price of the item for the two companies.
(b) what additional discount percent must be offered by the company that sells at higher net price in order to meet the competitor's price?


30% of RM100 is 0.30 × RM100 = RM30. Thus Softee Trading sells the item for RM100 - RM30 = RM70.

What is the selling price if Kinky Trading reduces their price of RM90 by 25%? What is the selling price if they then reduce that amount by 10%?
