Let original cost price of the goods be Rs. 100
He marked his goods at 50% above the cost price,
∴ Marked price of the goods = Rs. 150
He gives a discount of 20% on marked price,
∴ Selling Price = 150 × (80/100) = Rs. 120
? He weighs 20% less
∴ Actual cost price = 100 - (20% of 100) = Rs. 80
Profit = SP - CP = 120 - 80 = Rs. 40
∴ Profit percentage = $(\frac{{80{\rm{\;}} - {\rm{\;}}40}}{{80}} \times 100 = 50\%)$
