Answer 1

Answer:

38.09%

Step-by-step explanation:

Let the amount be 100

Discount of 6% = 100 - 100/100 * 6

                          = 100 - 6

                          = 94

Now,

Discount of 10% = 94 - 94/100 * 10

                            = 94 - 9.4

                            = 84.6

Now,

Discount of 15% = 84.6 - 84.6/100 *  15

                           = 84.6 - 12.69

                           = 71.91

Discount = 100 - 71.91

                = 38.09

Discount% = 38.09/100 *100

                  = 38.09%
