We know that inertia is defined by the mass of the body. So the body with more mass/weight will have more inertia.

(a) In the case of a rubber ball and a stone of the same size, the stone will have greater mass, so its inertia will be greater as compared to the rubber ball.

(b) A train has much more mass as compared to a bicycle, so the inertia of the train is greater.

(c) A five rupee coin has more weight than one rupee coin, so the inertia of a five rupee coin is greater.
