Answer 1

Answer:

Single discount = 28%

Step-by-step explanation:

You can find this by the formula,

(1 - d/100) = (1 - d1/100)(1 - d2/100)(1 - d3/100)- - - -

Given, d1 = 20%

d2 = 10%

d is the single discount we have to find.

Substituting the values,

1 - d/100 = (1 - 20/100)(1 - 10/100)

1 - d/100 = 80/100 * 90/100

1 - d/100 = 72/100

d/100 = 1 - 72/100

d/100 = 28/100

d = 28%
