Average weight of 15 persons is 30 kg.
A new person whose weight is 78 kg joins the group.
To find:
The average weight of 16 persons.
Solution:
The total weight of 15 persons is 15 * 30 = 450 kg.
When the new person joins the group, the total weight becomes 450 + 78 = 528 kg.
The average weight of 16 persons can be calculated by dividing the total weight by the number of persons:
Average weight of 16 persons = (Total weight of 16 persons) / (Number of persons)
= 528/16
= 33 kg
Therefore, the average weight of 16 persons is 33 kg.
