Correct answer: A

Solution: Find the price of silver per gram.

  1. Let the price of silver per gram be x.

  2. Total parts = 2 (gold) + 3 (silver) = 5.

  3. Write the weighted average equation for the mixture price:

    (2*3400 + 3*x) / 5 = 2350

  4. Multiply both sides by 5: 6800 + 3x = 11750

  5. Solve for x: 3x = 11750 - 6800 = 4950, so x = 4950 / 3 = 1650.

Therefore, the price of silver per gram is 1650 rupees.
