Correct Answer: 100 kg


Solution : The average weight of 15 people increased by 3.2 when a new person replaced a 52 kg person.
Weight of new person = previous person weight + Increased weight × number of persons
According to the formula,
Weight of new person = 52 + 3.2 × 15 = 52 + 48 = 100
The weight of the new person is 100 kg
Hence, the correct answer is 100 kg.
