A shopping mart offers four different discounts schemes on the sale of an object as follows:
(1) A discou t 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?
Explanation:
Correct Option is 2:
Scheme I. A discount of 30%
= 30%
Scheme II. Two successive discounts of 15%
= 15+ 15 - (15 x 15)/100
= 30 -2.25
= 27.75%
Scheme III. Buy 2 get 1 free
So, effective discount for scheme B is = (Article get free)/(Total articles) x 100
= 1/(1+2) x 100 = 33.33%
Scheme IV. Buy 5 get 3 free
So, effective discount for scheme A is = (Article get free)/(Total articles) x 100
= 3/(53) x 100 = 37.5%
Scheme (4) has the maximum discount percentage.
