Answer 3

Calculating the Average Age of the Team

Given that there are 16 children in the team, with a total age of 148, and the boys are 10 years old while the girls are 8 years old, we can calculate the average age of the team.

First, let's find the total age of the boys and girls in the team: - Total age of the boys = 10 years * (number of boys) - Total age of the girls = 8 years * (number of girls)

Then, we can use the total age of the team and the total age of the boys and girls to calculate the average age of the team.

Calculation Steps

1. Total age of the boys = 10 years * (number of boys) = 10 * (number of boys) 2. Total age of the girls = 8 years * (number of girls) = 8 * (number of girls) 3. Total age of the team = Total age of the boys + Total age of the girls = 10 * (number of boys) + 8 * (number of girls) 4. Average age of the team = Total age of the team / 16 (total number of children in the team)

Now, let's calculate the average age of the team.

Calculation

Total age of the boys = 10 years * (number of boys) = 10 * 12 = 120 Total age of the girls = 8 years * (number of girls) = 8 * 4 = 32 Total age of the team = Total age of the boys + Total age of the girls = 120 + 32 = 152 Average age of the team = Total age of the team / 16 = 152 / 16 = 9.5

The average age of the team, before 4 boys leave, is 9.5 years.

After 4 Boys Leave

If 4 boys leave the team, the total number of children in the team becomes 16 - 4 = 12.

To find the new average age of the team, we can use the total age of the remaining boys and girls and the new total number of children in the team.

Calculation

Total age of the remaining boys = 10 years * (number of remaining boys) = 10 * 8 = 80 Total age of the girls remains the same = 8 * 4 = 32 Total age of the team = Total age of the remaining boys + Total age of the girls = 80 + 32 = 112 Average age of the team after 4 boys leave = Total age of the team / 12 = 112 / 12 = 9.33

The average age of the team, after 4 boys leave, is 9.33 years.
