Answer:
Correct Answer: 22. Level will come down.
Solution:
- When stones were floating with boat, they will be displacing water of volume (say $V _1$ ) whose weight should be equal to weight of stones. When the stones sink, they will displace water of volume (say $V _2$ ) whose volume is equal to the volume of stones. But since density of water is less than the density of stones.
$\therefore \quad V _1>V _2$ or level will fall.
