Raman buys 18 kg of rice at ₹35 per kg and 30 kg of rice at ₹39 per kg. Find the average price (in ₹) per kg of the total rice.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 37.5.
Total cost = (18 × 35) + (30 × 39) = 630 + 1170 = 1800
Total quantity = 18 + 30 = 48 kg
Average price = 1800/48 = ₹37.50/kg
