In what ratio must the grocer mix two types of pulses costing ₹ 15/ kg and ₹ 20/ kg respectively so as to get a mixture of pulses costing ₹ 16.50/ kg ?

Solution & Step-by-step Explanation

Using the rule of alligation: * Cost of cheaper pulses (C) = ₹ 15 * Cost of dearer pulses (D) = ₹ 20 * Mean price (M) = ₹ 16.50 \frac{Quantity of Cheaper}{Quantity of Dearer} = \frac{D - M}{M - C} \frac{Quantity of Cheaper}{Quantity of Dearer} = \frac{20 - 16.50}{16.50 - 15} = \frac{3.50}{1.50} = \frac{35}{15} = \frac{7}{3} Thus, the required ratio is 7 : 3 .
