Restaurants A, B, C, and D give the following offers:
A: one mocktail free for every two purchased
B: one mocktail free for every three purchased
C: two mocktails free for every six purchased
D: 30% discount on each mocktail
If all restaurants have the same marked price for each mocktail, in which restaurant would you pay the least if you drank eight mocktails?
Given:
Let price of one mocktail = ₹1 (assume)
Total required = 8 mocktails
Formula:
Effective cost = amount paid / items received
Solution:
A: Buy 2 get 1 free → 3 for ₹2
For 8 mocktails:
6 mocktails → pay for 4
Remaining 2 → pay for 2
Total cost = 6
B: Buy 3 get 1 free → 4 for ₹3
For 8 mocktails:
8 = two sets → pay for 6
C: Buy 6 get 2 free → 8 for ₹6
D: 30% discount → pay 70%
Cost = 8 × 0.7 = 5.6
Compare:
A = 6
B = 6
C = 6
D = 5.6
Least cost = D
Final Answer: (d)
