  • a) 50
  • b) 48
  • c) 46
  • d) 44

correct answer : c)

Explanation :

Total Cost = (4 × 40) + (6 × 50) = 160 + 300 = ₹460.
Total Quantity = 4 + 6 = 10 kg.
Price per kg = 460 / 10 = ₹46.

कुल लागत = (4 × 40) + (6 × 50) = 160 + 300 = ₹460।
कुल मात्रा = 4 + 6 = 10 किग्रा.
कीमत प्रति किलो = 460/10 = ₹46.
