Correct Answer: 52%
Solution :
Given: First discount = 40% and second discount = 20%
Net discount = $(x+y-\frac{xy}{100})$%, where $x$ and $y$ are two successive discounts.
= $40+20-\frac{\text{40×20}}{100}$
= $60-\frac{\text{800}}{100}$
= $60-8$
= $52$
So, the net discount = 52%
Hence, the correct answer is 52%.
