Answer 2

Answer:

28.09%

e is the  correct option.

Step-by-step explanation:

Let us suppose the marked price is Rs 100

There is a 6% discount means that  the discount on Rs 100 is Rs 6

Now, second discount is 10% on (100-6)=Rs 94 is Rs 9.4

Finally the discount is 15% on (100-6-9.4) = Rs 84.6 is 84.6 × 0.15 = 12.69

Hence, the equivalent discount is given by

(6 + 9.4 +12.96)

= 28.09%

e is the  correct option.
