- Find the sum of age of 5 students.
Sum of age of 5 students = average age of 5 students * number of students
= 10 * 5
= 50
- Now, find the sum of age of 4 students, by subtracting the age of given student from the sum of 5 students.
Sum of age of 4 students = 50 - 6
= 44
- Now, find the average age of 4 students.
