means the second discount is not on the initial price, but is on the reduced price after the first discount.
Let us assume that the initial price is $ 100. The first discount of 40% reduced the price to $ 60.
The next discount of 20% on this reduced price of $ 60 is:
= [20 X 60] / 100
After this discounted amount of $12 is deducted from $60, the sales price is $ 48.
So, the Successive discounts of 40% and 20% have reduced the listed price by $ 52.
So, as the percent of the listed price of $ 100, it is $ 52.
So, the answer is (C).
