Correct Answer - Option 1 : 3 : 5

**Given :**

Basmati rice costing Rs. 40 per kg be mixed with India gate rice costing Rs. 48 per kg

Profit is 20%

Selling price is Rs. 54

**Formula: **

Selling price = (100 + profit) × cost price/100

**Solution: **

Let the cost price of whole mixture be Rs. x.

⇒ x = 54 × (100/120)

⇒ x = Rs. 45

⇒ Required ratio = (48 – 45)/(45 – 40)

⇒ Ratio = 3 : 5

**∴**** Required ratio is 3 : 5.**
