    Please find solution below... Actually the weight in air is the true weight but as the mineral is in the water both buoyant and gravity force acts on it and the gravity effect reduce it's weight or one can say that the archimedes principle is applied which says that any material or body when immersed wholly or partially in any liquid, it will displace the liquid equal to it's volume (or weight), so the weight is reduced in the water. The equation used for this question was the one that jolly applied in specific gravity calculation(just by using basic fluid mechanics i would say). Also one correction: This question is from jam 2015 not jam 2019.
