Explanation:

Let’s break this down:

- When you get two successive discounts, the overall discount isn’t just 12% + 8%. It’s a bit less because the second discount is applied to the already reduced price.

- Here’s how to find the equivalent single discount:

Equivalent Discount (%) = a + b – (ab/100)

Where a = 12, b = 8

- Plug in the numbers:

= 12 + 8 – (12×8)/100

= 20 – 0.96

= 19.04%

- So, let’s look at the options:

- Option 1: 18.8% ? Too low.

- Option 2: 19.04%

- Option 3: 19.4% ? Slightly high, not correct.

- Option 4: 19.8% ? Too high.

- Option 2 is absolutely correct.
