See i will tell u the theory about it. See is a body is in the are the a gravitational force is acting on it but as in the question its said that its weight reduces to 310gf. That means that an external force or upthrust is acting on it. And your answer is that the fluid displaced by body os the upthrust acting on it. And pressure is equal to mass per unit volume.
