RRB JE 2025 CBT 2 Mechanical and Allied Engg Question Paper English (2-Jul-2026) (Shift-1)
The correct answer is

Salt only

In a solution:

  • Solute = the substance that is dissolved (present in smaller quantity) → Salt
  • Solvent = the substance that does the dissolving (present in larger quantity) → Water
  • Solution = the homogeneous mixture formed (salt water)

Here, 10 g of salt is dissolved in 100 mL of water → salt is the solute.
