The marked price of watch was 820 Rs. A man bought the watch for 570.72 Rs. after getting two successive discounts, of which the first was 20%, then the second discount was :
[A]11%
[B]13%
[C]15%
[D]18%
13%
Total discount = (820 – 570.72) = 249.28 Rs.
First discount $latex = 820\times \frac{20}{100} = 164\ Rs.&s=1$
∴ Second discount = (249.28 – 164) = 85.28 Rs.
Price of the article after first discount = (820 – 164) = 656 Rs.
If the second discount be x%, then x% of 656 = 85.28
$latex => x = \frac{85.28\times 100}{656} = 13\%&s=1$
Hence option [B] is correct answer.
