Lou's mother bought a full bag of rice for 4000 only and sold it for 4200. What was percentage profit
To calculate the percentage profit, we need to use the formula:
Percentage Profit = ((Selling Price - Cost Price) / Cost Price) * 100
In this case:
Selling Price = 4200
Cost Price = 4000
Percentage Profit = ((4200 - 4000) / 4000) * 100
Percentage Profit = (200 / 4000) * 100
Percentage Profit = 0.05 * 100
Percentage Profit = 5%
Therefore, Lou's mother made a 5% profit on the sale of the rice.
