Correct Answer: 20 percent
Solution :
According to the question,
Marked Price = 150% of cost price
$\therefore$ $\text{MP} = 1.5\text{C}$
After a 20% discount, the selling price (SP) is given by:
SP $=$ Marked Price $−$ Discount
⇒ SP $=1.5\text{C}−0.2\times1.5\text{C}=1.2\text{C}$
⇒ Profit $=$ SP $−$ CP $=1.2\text{C}−\text{C}=0.2\text{C}$
Profit Percentage = $\frac{\text{Profit}}{\text{Cost Price}}\times 100$
$=\frac{0.2\text{C}}{C}\times 100$%
⇒ Profit Percentage = 20%
Hence, the correct answer is 20 percent.
