Successive Discount

Successive discount: Successive discount is the discount offered on the discount. It is similar to compound interest (interest on interest).

Illustration:  In a store the successive discounts offered on a bag are 10% and 20%. The store price of the bag is Rs 570. Then calculate the selling price of the bag.

Solution: Successive discounts offered on the bag = 10% and 20%

Both percentage changes are positive: x; and; y ;are; negative; and ;net; decrease =-x-y+frac{xy}{100};%

Total discount offered on the bag

              =-10 - 20 + frac{10 times 20}{100}%

             =-30 + frac{200}{100}%

            =-30 + frac{200}{100}%

           =-30+2=-28%

   Discount = 28% of Rs 570

                =frac{28}{100}; times ;570= Rs;159.6

 Selling price = store price – discount

                  = Rs 570 - Rs 159.6

                  = Rs 410.4
