To find a single equivalent discount for multiple successive discounts, you can use the following formula:

Equivalent Discount = 1 - (1 - d1) * (1 - d2) * (1 - d3)

Here, d1 = 10% or 0.10, d2 = 12% or 0.12, and d3 = 15% or 0.15.

- Calculate:

1. First, calculate (1 - d1) * (1 - d2):

(1 - 0.10) * (1 - 0.12) = 0.90 * 0.88 = 0.792

2. Then, multiply this result by (1 - d3):

0.792 * (1 - 0.15) = 0.792 * 0.85 = 0.6732

3. Finally, find the equivalent discount:

1 - 0.6732 = 0.3268 or 32.68%

- Option 1: 32.68%

- Option 2: 34.17%

- Option 3: 37%

- Option 4: 35.36%
