The cost prices of articles A and B are ₹1200 and ₹1600 respectively. The selling price of article A is ₹1380 and the total profit on selling both the articles is 25%. What is the profit percentage on selling of article B?

32.5

The cost price of articles A and B = 1200 + 1600 = Rs. 2800

The selling price of articles A and B = cost price × (100 + profit)% = 2800 × 125% = Rs. 3500

The selling price of A + the selling price of B = 3500

1380 + the selling price of articles B = 3500

The selling price of articles B = Rs. 2120

Profit % on article B = \(\frac{2120 - 1600}{1600}\) × 100 = 32.5%
