A shopkeeper mixes 15 kg of sugar costing Rs.11/kg with 22 kg of sugar costing Rs.12/kg. What is the cost (in Rs.) per kg of the mixture? (Rounded off to 2 decimal places)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 3 i.e. 11.59.
Cost of 15 kg sugar = 15 × 11 = ₹165
Cost of 22 kg sugar = 22 × 12 = ₹264
Total cost = ₹165 + ₹264 = ₹429
Total weight = 15 kg + 22 kg = 37 kg
Cost per kg = 429/37 ≈ 11.59
