Special offer: 3 items for the price of 2.5 items. We’ll compare each item’s deal to this offer.

  Beans 
 7 for 5 
 2.14 
 No 
 
  Pasta

  Flour 
 6 for 5 
 2.5 
 Yes

Calculations:    
Beans: 7 for 5 → 3 for  \frac{5}{7} \cdot 3 \approx 2.14 . 
Pasta: 3 for 2 → 3 for 2. 
Rice: 5 for 3 → 3 for  \frac{3}{5} \cdot 3 = 1.8 . 
Olive Oil: 4 for 3 → 3 for  \frac{3}{4} \cdot 3 = 2.25 . 
Flour: 6 for 5 → 3 for  \frac{5}{6} \cdot 3 = 2.5 .

Only flour matches the offer (2.5).
