Expert Answer:

This question is similar to the question that we give a push to 2 bodies which will move faster and the answer is as simple as the body having more mass will stop before than the body having less mass. Similarly, in this case we need to see the moment of inertia of the two bodies that is the raw egg and the boiled egg. Since in a boiled egg, the distribution is uniform and in the raw egg we can assume that the liquid will come towards the surface due toi the force during movement, hence the moment of inertia of the raw egg will be more and hence it will stop earlier and hence the Boiled egg will rotate for longer time.
