The concentration of sucrose will decrease.

Explanation:

The balloon contains 50% sucrose solution.

Diffusion is the net movement of the substance from the region of the higher concentration to the region of the lower concentration.

Given that the membrane is only permeable to water not sucrose. So, movement of sucrose will not take place. When the balloon is placed in a beaker of water, by the process of diffusion, the water moves from beaker to balloon and thus, the balloon will expand and the concentration of sucrose solution will decrease.
