according to newton's second law:
$$Fnet=m \times a$$
here $$Fnet=m \times g-Bforce$$
hence,$$m \times g - Bforce=m \times a$$.....(i)
here;
$$Bforce=V \times \rho(liquid)\times g$$
find the volume of man,by applying this formula
$$V=mass \div density$$
put this value in equation (i) and find acceleration(a)...this gives you numeric value of..
