Question

A dicount series of 10,20,40 % is equal to the single discount of

Answer 1

Answer:

56.8%

Let 100 be the number you are using the continuos discount on

10% of 100 = 10

100-10=90

20% of 90 = 18

90-18= 72

40%of 72 = 28.8

72-28.8 = 43.2

That means with these discounts you will have to pay 43.2 rupees instead of 100 rs

If you have to use one discount it would be

100-43.2= 56.8
