If the purchase amount is Rs 20000 and sell price is Rs 16000 then loss is how much percent

To calculate the percentage loss we first find the actual loss which is equal to purchase price minus selling price. In this case purchase price is Rs 20000 and selling price is Rs 16000 so the loss is Rs 4000. Next the percentage loss is found by dividing the loss by the purchase price and multiplying by one hundred. That is 4000 divided by 20000 multiplied by 100 which equals 20 percent. This shows the seller faced a significant loss on the deal. Calculating profit or loss percentages is a common concept in business accounting and competitive exams.
