Detailed Solution
Download Solution PDFGiven:
Cost of rice 1 = ₹25/kg
Cost of rice 2 = ₹40/kg
Ratio of rice 1 to rice 2 = 3:2
Formula Used:
Cost of mixture per kg = (Cost of rice 1 × Quantity of rice 1 + Cost of rice 2 × Quantity of rice 2) / (Quantity of rice 1 + Quantity of rice 2)
Calculation:
Cost of mixture per kg = (25 × 3 + 40 × 2) / (3 + 2)
⇒ Cost of mixture per kg = (75 + 80) / 5
⇒ Cost of mixture per kg = 155 / 5
⇒ Cost of mixture per kg = 31
∴ The correct answer is option (1).
