Find the percentage profit (on selling price) if the cost price = $405 and selling price = $615?
To determine the percentage of profit:
The cost price = $405 (given).
Sold price = $ 615 (given).
This sale gives a profit as the selling price is higher than the cost price.
Therefore the amount of profit = selling price - cost price = $(615-405) = $210.
Therefore the percentage of profit = (amount of profit/cost pice)100 = (210/405)100 = 21000/405 = 1400/27 = 51.85%.
Therefore , the percentage of profit in this sale is 51.85%.
