The marked price of a clock is 160 Rs, after two successive discounts a customer buys it for 122.40 Rs. If first discount is 10%, then what would be the second discount:
[A]10%
[B]12%
[C]15%
[D]18%
15%
Given that the list Price = 160 Rs.
After 10% discount Selling Price $latex = \frac{90}{100}\times 160 = 144 Rs.&s=1$
Now, Let the other discount = x%
$latex \therefore \frac{100-x}{100}\times 144 = 122.40 Rs. &s=1$
$latex => 100-x = \frac{12240}{144}&s=1$
$latex => 100 – x = 85$
$latex => x = 100 – 85 = 15\%$
Hence option [C] is correct answer.
