A shopkeeper announces the following three discount schemes for the purchase of an article. Which of these schemes is the best for a customer?
A. Two successive discounts of 15% and 18%
B. Buy 6 articles and get 2 free
C. A flat discount of 30%
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Scheme A.
A. Two successive discounts of 15% and 18%
successive discounts = x + y - xy/100
= 15 + 18 - (15 × 18)/100
= 30.3%
B. Buy 6 articles and get 2 free
Free article/Total article × 100
= 2/8 × 100
= 25%
C. A flat discount of 30%
So, Scheme A is best for the customer
