In a discount scheme, there is 50% discount on the marked price of Rs.500, but at the end it is sold for Rs.200. What additional discount did the customer get?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 20%.
Price of the article after 50% discount = 500 × (100 - 50)/100 = 500 × 50/100 = Rs.250
Let the additional discount given be x
Now, according to the question
⇒ 250 × (100 - x)/100 = 200
⇒ (100 - x) = (200 × 100)/250
⇒ 100 - x = 80
⇒ x = 100 - 80
⇒ x = 20%
