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.
