the cost price of 12 candles is equal to the selling price of 15 candles. find the loss per cent

Now I did the bottles one, you do this one.

the cost price 12 candles, a man gains an amount equal to the selling price of 15 candles.Find the loss per cent

To find the loss percentage, we need to determine the difference between the cost price and the selling price, and then calculate it as a percentage of the cost price.

Given that the cost price of 12 candles is equal to the selling price of 15 candles, we can assume a common unit price for each candle.

Let's say the cost price of one candle is 'CP' and the selling price is 'SP'.

According to the given information, the cost price of 12 candles is equal to the selling price of 15 candles:

12 * CP = 15 * SP

To find the loss percentage, we need to calculate the loss.

Loss = Cost Price - Selling Price

Since the selling price is greater than the cost price (as the cost price of 12 candles is equal to the selling price of 15 candles), the loss will be negative. Therefore, we need to consider the magnitude of the loss by taking the absolute value.

Loss = |Cost Price - Selling Price|

Now, let's substitute the given information into the equation:

Loss = |12 * CP - 15 * SP|

Since the loss is a percentage, we can calculate the loss as a fraction of the cost price:

Loss Percentage = (Loss / Cost Price) * 100

Substituting the value of the loss and cost price into the equation:

Loss Percentage = (|12 * CP - 15 * SP| / (12 * CP)) * 100

The resultant expression will provide the loss percentage.
