Question

a discount series of 10% 20% and 40% is equivalent to the single discount of dash​

Answer 1

Answer:

Let the initial price = 100

10% discount = 100*10/100 = 10

Remaining amount = 100 - 10 = 90

20% discount = 90*20/100 = 18

Remaining amount = 90 - 18 = 72

40% discount = 72*40/100 = 28.8

Total discount = 10+18+28.8 = 56.8

Since the initial price is assumed as 100,

the single equivalent discount = 56.8%
