The mass of an object doesn't change when gravity changes.

Hence, the mass of the stone is still 30 kg \color{#3D99F6}{\boxed{30\ \text{kg}}} .

It would be better if the question says that the stone has a mass of 30 30 kg (should not be misinterpreted as 30 kg weight)

Kilogram is ALWAYS an unit of mass. Sometimes it is misinterpreted as an unit of weight. There is no need to state that we mean the mass of the object when we use kilogram.
