Question

Find the single discount equivalent to successive discount of 13% and 15% .

Answer 1

Lets take the List price as 100
SP after discount=100-(100×13/100)
                           =100-13
                           =87
SP after successive discount=87-(87×15/100)
                                              =87-(87×3/20)
                                              =87-13.05
                                              =73.95
Deduction in price(%)=(100-73.95) /100
                                  =26.05%
∴single discount equivalent to successive discount of 13% and 15% is 26.05%
