1. If the price of an item is increased by 10% and then decreased by 10%, the net effect on the price of the item is --
- A. an increase of 99%
- B. an increase of 99%
- C. an increase of 99%
- D. an increase of 99%
Answer: Option D
Explanation:
Let, price of the item = Tk.100
After 10% increase the price become = (100 + 10) = Tk.110
Then, after 10% decrease new price = 110 - 10/100×110 = Tk.99
Net decrease = 100 - 99 = Tk.1
