Question:
If the price of a certain product is first decreased by 35% and then increased by 20%, then what is the net change in the price of the product?
A20%
B25%
C22%
D30%
Answer:
C. 22%
Explanation:
Let the price of the product be Rs 100 When the price is decreased by 35%, it becomes 100 - 35% of 100 = 100 - 35 = 65 Then it is increased by 20%. It becomes 65 + 20% of 65 = 65 + 13 = 78 Net change in the price of the product = {(Original Price - Changed Price)/Original Price} × 100 = {(100 - 78)/100} × 100 = 22
