A scheme like ‘Buy 6, Get 2 Free’ on the same kind of articles with the same MRP attracts a _____ % discount.

Correct option is A

Given:
Number of items paid for = 6
Number of free items = 2
Formula Used:
Discount Percentage = $$\frac{Free\ Items}{Total\ Items}$$​ × 100
Solution:
Total items received = 6 + 2 = 8
Free items received = 2
Discount Percentage = $$(\frac{2}{8})$$​ × 100

Discount Percentage = $$(\frac{1}{4})$$​× 100
Discount Percentage = 25
Final Answer
