A market woman buys 10 oranges for 80 and sells them for 10 each. What is her percentage profit of loss
Let's calculate the total cost of 10 oranges for the market woman first.
Cost price of 10 oranges = 10 oranges * 80 = 800
Now, let's calculate the total selling price of 10 oranges for the market woman.
Selling price of 10 oranges = 10 oranges * 10 = 100
Profit = Selling Price - Cost Price
Profit = 100 - 80 = 20
Now, let's calculate the percentage profit.
Percentage Profit = (Profit / Cost Price) * 100
Percentage Profit = (20 / 800) * 100 = 2.5%
Therefore, the market woman made a profit of 2.5% by selling 10 oranges.
