Answer:
72 kg
Explanation:
The computation of the mass of the person is shown below:
As we know that
Water displaced weight = Raft weight + person weight
P_w.V = M_r + M_p
where
P_w denotes the water density i.e. 1000 kg/m^3
V denotes the volume of the water in m^3
Now
1000 × 0.224 = 152 + M_p
M_p = 224 - 152
= 72 kg
