C) Buy 6 and get 10.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. B.
A) Effective discount = x + y + xy/100
here, x = -24, and y = -27
Effective discount = -24 - 27 + 648/100
⇒ -51 + 6.48 = 44.52%
B) Buy 5 get 3 free
Discount% = Free items/Total items × 100
⇒ 3/8 × 100 = 37.5%
So, the effective discount for Scheme B is 37.5%.
C) Buy 6 and get 10
Discount% = Free items/Total items × 100
⇒ 4/10 × 100 = 40%
So, the effective discount for Scheme C is 40%.
Thus, The scheme that fetches the minimum discount percentage is Scheme B: Buy 5 get 3 free with a discount of 37.5%.
