In what ratio should a shopkeeper mix two types of rice, one costing ₹ \(20\) per kg and another costing ₹ \(40\) per kg to get a rice variety costing ₹ \(28\) per kg ?
- A \(3 : 5\)
- B \(3 : 2\)
- C \(3 : 4\)
- D \(4: 3\)
Answer & Solution
Correct Answer
(B) \(3 : 2\)
Step-by-step Solution
Detailed explanation
\( \text{Ratio} = \frac{C_2 - C_m}{C_m - C_1} \) \( = \frac{40 - 28}{28 - 20} \) \( = \frac{12}{8} \) \( = 3 : 2 \)
