Answer :

Final answer:

The weight of the boat is 242 kg.

Explanation:

The weight of the boat is 242 kg.

Let the weight of the boat be 'B' kg. According to the given information, the average weight of the boat and the persons is 52 kg. The average weight of the five persons is 38 kg. This means:

  1. Total weight of boat + 5 persons = 52 * 6 = 312 kg
  2. Total weight of 5 persons = 5 * 38 = 190 kg
  3. Therefore, weight of boat (B) = Total weight - Weight of 5 persons = 312 - 190 = 122 kg

So, the weight of the boat is 122 kg.
