Scheme I. Two successive discounts of 20% and 25%

So, effective discount for scheme I is = 20 + 25 - (20 × 25)/100 = 45 - 5 = 40%

Scheme II. Buy 5 get 3 free

So, effective discount for scheme II is = (Article get free)/(Total articles) × 100 = 3/(5 + 3) × 100 = 37.5%

Scheme III. Buy 5 get 6

So, effective discount for scheme III is = (Article get free)/(Total articles) × 100 = 1/(6 ) × 100 = 16.67%

So, answer is Scheme I.
