The list price (marked price) of an article is Rs. 900 and is available at two successive discounts of 20% and 10%. The selling price of the article, in rupees, is :
-
- 640
- 648
- 720
- 738
Correct Option: B
Given that , List price (marked price) of an article = Rs. 900
Single equivalent discount for a% and b% = | a + b - | % | |||
100 |
Here , a = 20 , b = 10%
Single equivalent discount = | 20 + 10 - | % | |||
100 |
Single equivalent discount = (30 – 2)% = 28%
∴ S.P. of article = (100 – 28)% of Rs. 900
⇒ S.P. of article = 72% × Rs. 900
S.P. of article = Rs. | = Rs. 648 | |||
100 |
