Answer 1

In one of USTP IT section, 70% of the students are men and 30% of the students are women. If the average age of the men is 30 and the average age of the women is 40, what is the average age of all the students.

Answer 2

Given,
Percentage of males =30%
Percentage of females=40%
Average age of men=30
Average age of women=40


To find,
Average age of all the students

Solution,
Average age of all students = total number of ages /number of groups

Average age of all students =(average age of men+average age of women)/2
=(30+40)/2
=70/2
=35

Therefore, the average age of all students is 35.
