The price of 10 kilograms of apples is the same as the price of 24 kilograms of rice. Additionally, the cost of 6 kilograms of flour is equal to the cost of 2 kilograms of rice. If the price per kilogram of flour is Rs. 20.50, what is the combined cost of purchasing 4 kilograms of apples, 3 kilograms of rice, and 5 kilograms of flour?

Explanation

Let the price per kilogram of apples be Rs. a and that of rice be Rs. r. From the problem, 10a = 24r, so a = (12/5)r. Also, the cost of 6 kg flour equals the cost of 2 kg rice, so 6 × 20.50 = 2r, which gives r = Rs. 61.50. Therefore, a = (12/5) × 61.50 = Rs. 147.60. The total cost is calculated as (4 × 147.60) + (3 × 61.50) + (5 × 20.50) = 590.40 + 184.50 + 102.50 = Rs. 877.40.
