15 kg of superior quality of wheat is mixed with 5 kg of inferior quality of wheat. The price of superior quality and inferior quality wheat is ₹80 and ₹60, respectively. Find the average price per kg of the mixture.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e ₹75.
Superior: 15 × 80 = ₹1200
Inferior: 5 × 60 = ₹300
Total cost = 1200 + 300 = ₹1500
Total quantity = 15 kg + 5 kg = 20 kg
Average price = Total cost ÷ Total quantity = 1500 ÷ 20 = ₹75
