A man is sitting in a boat which is floating in a pond. If the man drinks same water from the pond, the level of water in pond will

rise a little

go down

remains same

none of these

Solution

Let say, he drinks $m$ mass of water, due to which the weight of man and boat increases and level of pond decreases. Now due to increase in mass, boat will displaced more volume and the level of water will rise. since the water was removed from the pond is equal to the water displaced by the man and boat, the level of water in the pond remains same.
