Anil bought two articles A and B at a total cost of Rs. 10,000. He sold the article A at 15% profit and the article B at 10% loss. In the whole deal, he made no profit or no loss. Find the selling price of the article A.

Let cost price of A = x, then cost price of B = (10000 - x). Selling price of A = 1.15x (15% profit), selling price of B = 0.9(10000 - x) (10% loss). Since there's no profit or loss overall: 1.15x + 0.9(10000 - x) = 10000. Solving: 1.15x + 9000 - 0.9x = 10000, so 0.25x = 1000 and x = 4000. Therefore, selling price of A = 1.15 × 4000 = Rs. 4,600.
