answerIf the cost price of 15 tables be equal to the selling price of 20 tables, the loss per cent is?

Let's solve this step by step:

Step 1: Assume the cost price of each table is $1. Therefore, the cost price of 15 tables is$15.

Step 2: According to the problem, the selling price of 20 tables is also $15. So, the selling price of each table is$15/20 = $0.75.

Step 3: The loss on each table is the cost price minus the selling price, which is $1 -$0.75 = $0.25.

Step 4: The loss percentage is calculated by dividing the loss by the cost price and then multiplying by 100. So, the loss percentage is ($0.25/$1) * 100 = 25%.

Therefore, the loss percent is 25%.
