1. The price of a DVD Player is discounted by 10 percent, and the reduced price is then discounted again by 10 percent. The series of successive discounts is equivalent to a single discount of ----
- A. 20%
- B. 20%
- C. 20%
- D. 20%
Answer: Option B
Explanation:
Let the initial price be 100.
Now, first discounted price = 100 - 10% of 100 = 100 - 10 = 90
Again, second discounted price = 90 - 10% of 90 = 90 - 9 = 81
Actual discount = (100 - 81)% = 19%
