Question

find a single disount equivalent to a series of 10%,20% and 30%​

Answer 1

Answer:

49.6 %

Step-by-step explanation:

a=10%   b=20%    c=30%

Successive discount formula = a + b - ab/100

First calculate the successive discount of a and b

                                                =10 +20 -200/100

                                                =30 -2 = 28%

Afterwards calculate the successive discount of 28% and 30%

                                                 =28 + 30 - 840/100

                                                 = 58 - 8.4

                                                 = 49.6 %
