Answer 1

Given:

Discounts offered: 10%, 20%, and 50%

Formula Used:

Single Equivalent Discount = 1 - (1 - d1) × (1 - d2) × (1 - d3)

Calculation:

Let d1 = 10% = 0.10

Let d2 = 20% = 0.20

Let d3 = 50% = 0.50

Single Equivalent Discount = 1 - (1 - 0.10) × (1 - 0.20) × (1 - 0.50)

Single Equivalent Discount = 1 - 0.90 × 0.80 × 0.50

Single Equivalent Discount = 1 - 0.36

Single Equivalent Discount = 0.64

Single Equivalent Discount = 64%

The single discount equivalent to the given discounts is 64%.
