Let the fruit seller purchase 100 mangoes in Rs 100 Cost price of 1 mango = Rs 1 He sell 50% of mangoes = 100 × 50% = 50 mangoes At a profit of 50% of total cost. So profit = total cost × 50% = 100 × 50/100 = Rs 50 ∴ Selling price of 50 mangoes = C.P + Profit = 50 + 50 = Rs 100 So profit % = 50/50 × 100 = 100% He sells 50 mangoes at the profit of 100% He sells 80% of the remaining mangoes = 80/100 × 50 = 40 mangoes Cost price of 40 mangoes = Rs 40 Profit % = 100 × 1/4 = 25% Selling price of 40 mangoes = 125/100 × 40 = Rs 50 So overall cost price = Rs 100 of 100 mangoes Overall selling price = 100 + 50 = Rs 150 So profit = 150 – 100 = Rs 50 Profit % =  50/100 × 100 = 50%
