An article is listed at 920 Rs. A customer pays 742.90 Rs. for it after getting two successive discounts. If the rate of first discount is 15%, then what would be the rate of second discount :
[A]3%
[B]5%
[C]8%
[D]12%
5%
Total discount = (920 – 742.90) = 177.10 Rs.
First discount = 15%
∴ Discount = 15% of 920
$latex = \frac{920\times 15}{100} = 138\ Rs.&s=1$
Price after this discount = 920 – 138 = 782 Rs.
Remaining Discount = 177.10 – 138 = 39.10 Rs.
Let the second discount be x %.
$latex \therefore \frac{782\times x}{100} = 39.10&s=1$
$latex => x = \frac{39.10\times 100}{782} = 5\%&s=1$
Hence option [B] is correct answer.
