Explanation:

- When two successive discounts are applied, they're not simply added together.

- First, calculate the effect of the 12% discount on the original price: 88% remains.

- Then, apply the second discount of 8% on the new price after the first discount.

- Calculate: 88% × 92% = 80.96% remains after both discounts.

- The single equivalent discount is thus 100% - 80.96% = 19.04%.

Options:

1. 18.8

2. 19.04

3. 19.4

4. 19.8

The correct single discount is 19.04%, matching Option 2.
