Step-by-step explanation:

Given  

By selling an article for rs. 300, a trader made a profit of 25%. Now, if the trader GIVES a successive discount of 15% and 10% on the existing  selling price, then how MUCH profit/loss does he EARN?​

Let the cost of the article be x and profit is 25%

25/100 = 0.25 + 1(article) = 1.25

So original price of article will be

(1.25) = 300

 x = 300 /1.25 = Rs 240

Now he made a profit of 25% of 240 = Rs 60

So total will be 240 + 60 = Rs 300

First 15% of 300 = 15/100 x 300 = 45

300 – 45 = Rs 255

Again 10% of 255 will be 10/100 x 255 = 25.5

255 – 25.5 = Rs 229.5

From Rs 240, now he has only Rs 229.50. So 240 – 229.50 = Rs 10.5.

So it a loss of Rs 10.5
