please explain cost price$50 loss 25%

To understand how to calculate the cost price when there is a loss percentage involved, we need to follow these steps:

Step 1: Start with the given selling price (in this case, $50) and the loss percentage (in this case, 25%).

Step 2: Calculate the amount of loss by multiplying the selling price by the loss percentage (in decimal form). In this case, $50 x 0.25 = $12.50.

Step 3: Subtract the amount of loss from the selling price to find the cost price. In this case, $50 - $12.50 = $37.50.

So, the cost price in this scenario is $37.50.

To summarize:
Cost Price = Selling Price - (Selling Price x Loss Percentage)
Cost Price = $50 - ($50 x 0.25)
Cost Price = $50 - $12.50
Cost Price = $37.50
