Detailed Solution
Download Solution PDFGiven:
Ratna buys:
10 kg of rice at Rs. 88 per kg
20 kg of rice at Rs. 187 per kg
Formula Used:
Cost of the mixture per kg = (Total cost of all rice) / (Total weight of all rice)
Calculation:
Cost of 10 kg rice at Rs. 88 per kg:
Total cost = 10 × 88 = Rs. 880
Cost of 20 kg rice at Rs. 187 per kg:
Total cost = 20 × 187 = Rs. 3740
Total cost of the mixture:
Total cost = 880 + 3740 = Rs. 4620
Total weight of the mixture:
Total weight = 10 kg + 20 kg = 30 kg
Cost per kg of the mixture:
Cost per kg = 4620 / 30
⇒ Cost per kg = 154
The per kg cost of the total mixture is Rs. 154
