A shopping mart offers four different discounts schemes on the sale of an object as follows:
(1) A discount of 30%
(2) Two successive discounts of 15%
(3) Buy 2, get 1 free
(4) Buy 5, get 3 free
Which discount scheme offers the maximum discount to a customer?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (4).
Scheme (1): Discount = 30%
Scheme (2):
Successive discounts of 15% and 15% = 15 + 15 - (15 × 15)/100 = 15 + 15 - 2.25 = 27.75%
Scheme (3):
Buy 2, get 1 free
Discount = (1/3) × 100 = %.
Scheme (4):
Buy 5, get 3 free
Discount = (3/8) × 100 = 37.5%
Therefore, the discount scheme that offers the maximum discount to a customer is Scheme (4).
