Question

4. The list price of a radio is 160. A man buys it for 122.40. He gets two successive discounts.
If the one is 10%, find the other one.
Ans. (15%)​

Answer 1

Answer:

Given that the list Price = 160 Rs.

After 10% discount Selling Price = \frac{90}{100}\times 160 = 144 Rs.

Now, Let the other discount = x%

\therefore \frac{100-x}{100}\times 144 = 122.40 Rs.

=> 100-x = \frac{12240}{144}

=> 100 - x = 85

=> x = 100 - 85 = 15\%
