Calculation of the average age:
To find the approximate average age for all the students of Class I and Class II, we need to calculate the total sum of ages and the total number of students in both classes.
Class I:
- Number of students: 12
- Average age: 20 years
The total sum of ages in Class I can be calculated by multiplying the average age by the number of students:
Total age in Class I = 20 years * 12 students = 240 years
Class II:
- Number of students: 16
- Average age: 23 years
The total sum of ages in Class II can be calculated by multiplying the average age by the number of students:
Total age in Class II = 23 years * 16 students = 368 years
Total:
To find the total average age for all the students, we need to add the total sum of ages in both classes and divide it by the total number of students.
Total sum of ages = Total age in Class I + Total age in Class II = 240 years + 368 years = 608 years
Total number of students = Number of students in Class I + Number of students in Class II = 12 students + 16 students = 28 students
Approximate average age:
To find the approximate average age, we divide the total sum of ages by the total number of students:
Approximate average age = Total sum of ages / Total number of students = 608 years / 28 students ≈ 21.71 years
Therefore, the approximate average age for all the students of Class I and Class II is approximately 21.71 years.

Total sum of ages = Total age in Class I + Total age in Class II = 240 years + 368 years = 608 years
Total number of students = Number of students in Class I + Number of students in Class II = 12 students + 16 students = 28 students
Approximate average age:
To find the approximate average age, we divide the total sum of ages by the total number of students:
Approximate average age = Total sum of ages / Total number of students = 608 years / 28 students ≈ 21.71 years
Therefore, the approximate average age for all the students of Class I and Class II is approximately 21.71 years.
