A shopkeeper offers the following two discount schemes.
A) Two successive discounts of 10% and 15%
B) Buy 5 get 2 free.
Which scheme has the maximum discount percentage?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. B.
A) Two successive discounts of 10% and 15%
Single discount of two successive discounts = x + y + xy/100
-10 - 15 + 150/100 = -25 + 1.5 = 23.5% [-ve sign shows discount]
B) Buy 5 get 2 free
Concept:
M.P. = S.P. + Discount
Discount % = Discount/M.P. × 100
Let M.P. of 1 good be Rs. x.
M.P. of 7 goods = 7x
Discount = Rs. 2x
Net discount % = {(2x)/7x} x 100 = 28.57%
The net discount is equal to 28.57%.
Thus, scheme B will give maximum discount
