Formula used:

Effective discount = x + y - (x × y)/100

effective discount = (Article get free)/(Total articles) × 100

Calculation:

Scheme I. Buy 3 get 4 free

So, effective discount for scheme A is = (Article get free)/(Total articles) × 100

= 4/(4 + 3) × 100 = 57.12%

Scheme II. Buy 5 get 6

So, effective discount for scheme B is = (Article get free)/(Total articles) × 100

= 6/(6 + 5 ) × 100 = 54.54%

A has the maximum discount percentage.
