To me, at least, "successive discounts" clearly means the second discount is on the already discounted price....

When the price is discounted 20%, 80% of the price remains. If the original price is x, then the discounted price after the first discount is 0.80x.

When THAT price is reduced by 12%, 88% of it remains. The price after the second discount is

The new price is 70.4% of the original price; the effective discount is 100-70.4 = 29.6%.
