The answer would be the size of the balloon would increase.
The balloon permeable to water but not sucrose, so only water will be move between the membrane. Since the balloon water is made of 50% sucrose, the solution should have higher osmotic pressure than the beaker that 100% water. This will make the water molecule from beaker move toward the balloon, decreasing its sucrose concentration and increase the balloon size.
The balloon is only permeable to water but not to sucrose, So the water will enter the balloon, but sucrose will not leave the balloon.
This means the concentration of water will increase, inside the balloon.
Permeable means being able to permeate any liquid or solution through itself.
The permeable membrane can pass through any liquid or solution through it.
Our cell is a semi-permeable membrane. It is only permeable to things that are useful for the cell, and denied access to unwanted things.
Thus, the water will enter the balloon, but sucrose can not pass through the balloon, so water concentration inside the balloon will increase.
