Question

An article is listed at Rs 850. A customer pays Rs 612 for it after getting two successive discounts. If the rate of first discount is 10%, the rate of 2nd discount is ?​

Answer 1

Given,

Listed price of an article is Rs.850

The customer pays Rs.612

The first discount is 10%

To find,

The percentage of second discount.

Solution,

The first discount amount = 850 × 10/100 = Rs. 85

The price after first discount = 850-85 = Rs. 765

The price after second discount = Rs. 612

The second discount amount = Price after first discount - Price after second discount = 765-612 = Rs. 153

Let,the second discount = x%

So,the second discount amount = 765 × x/100 = Rs. 765x/100

Now, if we compare the two values of the second discount,then we will get the following mathematical equation :

765x/100 = 153

x = 15300/765

x = 20

Hence,the second discount is 20%.
