Solution(By ExamCraze Team)

Let the five persons be A, B, C, D, E
According to the question,
= $$frac{A + B + C + D + E}{5}$$     = 38 kg
= A + B + C + D + E = 190 kg.....(i)
$$frac{{5,{text{persons}} + {text{Boat}}}}{6} = 52$$
5 persons + Boat = 312 kg.....(ii)
∴ Boat's weight = 312 - 190 = 122 kg
