What is the meaning of the word loss? Basically the word loss will come in consumer arithmetic chapter. Loss means suppose if you brought a product for x rupees and for some reason if you sell it to your friends or any other people for less than x rupees then we say that on whole transaction we got loss.

               For example, let us think that we brought table fan for 2000 rupees and after a week we sold it for 1800 rupees. Now if we observe this transaction we lost 200 rupees. So when we say that we get loss means if cost price is greater than selling price.

♥ Amir brought a TV for 15000 rupees. After 2 days he sold it for 10000 rupees then find the loss percentage.



                              Cost price = 15000

                              Selling price = 10000

Loss = cost price – selling price

         = 15000 – 10000

        = 5000

Therefore, based on loss percentage formula, we get

          Loss %        = (5000/15000) × 100%

                              = (1/3) × 100%

                              = (100/3) %

                              = 33.3333%

I hope you got the lost percentage formula.
