Osmosis is defined as the process by which the molecules of a solvent move through a semi permeable membrane from the region of lower concentration to the region of higher concentration. For the question given above, the concentration of 30% salt is greater than that of 10% in the cell, so the water molecules will move from the cell [region of lower concentration] into the salt solution [region of higher concentration]. The loss of water will make the cell to shrink and to become smaller.
