A store announces the following three schemes to sell its articles:
Which of these gives the maximum discount to the buyer?
A. Two successive discounts of 20% and 24%
B. Buy 5 get 3 free
C. Buy 13 get 7 free
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. A.
Successive discounts = x + y - xy/100
Buy x get y free, Discount % = Free item/Total item × 100
A. Two successive discounts of 20% and 24%
20 + 24 - (20 × 24)/100
= 44 - 4.8
= 39.2%
B. Buy 5 get 3 free
Discount % = 3/(5 + 3) × 100 = 37.5%
C. Buy 13 get 7 free
Discount % = 7/(13 + 7) × 100 = 35%
So, A gives the maximum discount to the buyer, i.e. 39.2%
