Question
An article has a cost price of Rs. 500 and is marked 80%
above its cost price. 'A' proposes to sell this article after two successive discounts of 15% and Rs. 30, while 'B' proposes to sell it after a single discount of 35%. What is the difference between the selling prices proposed by 'A' and 'B'?Solution
ATQ; 
Marked price of the article = 500 X 1.80 = Rs. 900 
 
Selling price proposed by 'A' = 900 X 0.85 - 30 = 765 - 30 = Rs. 735 
 
Selling price proposed by 'B' = 900 X 0.65 = Rs. 585 
 
So, required difference = 735 - 585 = Rs. 150
