31.60%

30.60%

32.80%

- To find a single equivalent discount for multiple discounts, we multiply the complements of the discounts and subtract from 100%.

- Complement of 20% is 0.80 (or 80%), for 10% is 0.90 (or 90%), and for 5% is 0.95 (or 95%).

- Multiply these complements: 0.80 * 0.90 * 0.95 = 0.684.

- Subtract the product from 1 (or 100%): 1 - 0.684 = 0.316.

- Convert this back to a percentage: 0.316 = 31.6%.

- Option:2, 31.60% is the correct equivalent single discount.
