The weight of the boat can be determined by first finding the total weight of the 5 persons and then subtracting it from the total weight of the boat and the persons sitting in the boat.

Let's assume the weight of the 5 persons sitting in the boat is x kg. According to the given information, the average weight of the 5 persons is 38 kg. Therefore, the total weight of the 5 persons is 38 kg multiplied by 5, which is 190 kg.

- Find the Total Weight of the Boat and Persons

The average weight of the boat and the persons sitting in the boat is given as 52 kg. Since the average is calculated by dividing the total weight by the number of items, we can use this information to find the total weight of the boat and the persons.

Let's assume the weight of the boat is y kg. According to the given information, the average weight is 52 kg. Therefore, the total weight of the boat and the persons is 52 kg multiplied by 6 (5 persons + 1 boat), which is 312 kg.

- Calculate the Weight of the Boat

To find the weight of the boat, we need to subtract the total weight of the 5 persons from the total weight of the boat and the persons.

312 kg - 190 kg = 122 kg

Therefore, the weight of the boat is 122 kg.

- Conclusion

The weight of the boat is 122 kg, which corresponds to option 'B'.
