Question : The list price (marked price) of an article is Rs. 900 and it's available at two successive discounts of 20% and 10%. The selling price of the article, in rupees, is:
Option 1: 640
Option 2: 648
Option 3: 720
Option 4: 738
Correct Answer: 648
Solution :
Given: The list price (marked price) of an article is Rs. 900 and it's available at two successive discounts of $a$ = 20% and $b$ = 10%.
Here, marked price = Rs. 900
So, after two successive discounts of 20% and 10%,
Selling price = Marked price$×(\frac{100-a}{100})×(\frac{100-b}{100})$ = $900×\frac{100-20}{100}×\frac{100-10}{100}$
⇒ SP = $900×\frac{80}{100}×\frac{90}{100}$ = Rs. 648
So, the selling price is Rs. 648.
Hence, the correct answer is 648.
