Quantity of sugar = 6 kg
Price of sugar per kg = Rs. 10
∴ Total cost = 10 × 6 = Rs. 60
Another quantity of sugar = 4 kg
Price of sugar per kg = Rs. 15
∴ Total cost = 15 × 4 = Rs. 60
⇒ Total cost of 10 kg of sugar = 60 + 60 = Rs. 120
⇒ Cost per kilogram = 120/10 = Rs. 12 per kilogram
Price of sugar per kg = Rs. 10
∴ Total cost = 10 × 6 = Rs. 60
Another quantity of sugar = 4 kg
Price of sugar per kg = Rs. 15
∴ Total cost = 15 × 4 = Rs. 60
⇒ Total cost of 10 kg of sugar = 60 + 60 = Rs. 120
⇒ Cost per kilogram = 120/10 = Rs. 12 per kilogram
