A man bought three articles for ₹3000/- each. He sold each article at 15% profit, 10% profit and 15% loss respectively. Find his overall profit or loss percentage.

3\(\frac{1}{3}\)% profit

Profit on 1st article = 3000 × 15% = 450

           IInd article =  3000 × 10% = 300

Loss on IIIrd article = 3000 × 15% = -450

                                                      ----------

                       Overall profit/loss  = 300

Overall profit % = \(\frac{300}{9000}\) × 100 = 3\(\frac{1}{3}\)%
