A trader sold a car to mr Brown for #1250, at a profit of 25%. How much profit did the trader make?

To find the profit made by the trader, we need to calculate 25% of the selling price.

Profit = 25/100 * 1250
Profit = 0.25 * 1250
Profit = 312.5

Therefore, the trader made a profit of #312.5.

To determine the profit made by the trader, we'll need to calculate the original cost of the car.

Let's assume the original cost of the car is represented by 'x'. The trader sold the car for #1250, which is 125% of the original cost (100% of the original cost plus a profit of 25%).

We can set up the following equation to represent this:

125% of x = #1250

To find the original cost, we need to divide both sides of the equation by 125% or 1.25 (since 125% is equivalent to 1.25):

x = #1250 / 1.25

Evaluating the right-hand side of the equation:

x = #1000

Thus, the original cost of the car was #1000.

To calculate the profit made by the trader, we can subtract the original cost from the selling price:

Profit = Selling Price - Original Cost
Profit = #1250 - #1000
Profit = #250

Therefore, the trader made a profit of #250.

To determine the profit made by the trader, we need to calculate 25% of the selling price of the car.

Step 1: Convert 25% to a decimal by dividing it by 100:
25% / 100 = 0.25

Step 2: Multiply the selling price (#1250) by the decimal equivalent of the profit percentage:
Profit = #1250 x 0.25

Step 3: Calculate the result:
Profit = #312.50

Therefore, the trader made a profit of #312.50.
