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%.
