A man purchases 20 dozens of toys at the rate of Rs.375 per dozen. He sold each one of them at the rate of Rs.33. What was his percentage profit?
Total amount for the purchase, Cost Price = 20×375=Rs.7500
Selling price = 20×12×33=Rs.7920
Profit = SP - CP
= 7920 - 7500 = Rs. 420
Profit percentage = ProfitCP×100=4207500×100=5.6%
