The list price of an article is Rs. 900. It is available at two successive discounts of 20% and 10%. The selling price of the article is :

1. Rs. 640
2. Rs. 648
3. Rs. 540
4. Rs. 548

Correct Option: B

Single equivalent discount for 20% and 10%

=		20 + 10 −	20 × 10		% = 28%
			100

Marked price of article = Rs. 900
S.P. of article = (100 – 28)% of 900

S.P. of article =	900 × 72	= Rs. 648
	100
