What is the discount percentage equivalent to three successive discounts of 12%, 10% and 5%?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 2 i.e. 24.76.
Let the marked price be 100x.
SP = MP × (100 - 12)/100 × (100 - 10)/100 × (100 - 5)/100
⇒ 100x × 88/100 × 90/100 × 95/100 = 75.24x
Now, overall discount = [(100x - 75.24x)/100x] × 100 = 24.76%
