A man bought two article for ₹3,000 each.He sold one article at 10% profit and the other at 5% loss.What is the total profit or loss percentage?

Cost price of each article = Rs 3000 

First article is sold at profit of 10% 

Selling price of first article = $$10\%\ of\ 3000+3000$$

$$\frac{10}{100}\times\ \ 3000+3000=₹3300$$

Second Article is sold at loss of 5%

Selling price of second article = $$3000-\frac{5}{100}\times\ 3000=₹2850$$

Total cost price = 3000 + 3000 = 6000

Total selling price = 3300 + 2850 = 6150

Required % = $$\frac{6150-6000}{6000}\times\ 100=2.5\%$$

There would be a profit because selling price is greater than cost price.

Hence, Option B is correct.
