Answer:
62
Step-by-step explanation:
Concept
In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
SOLUTION
Total age of student=20*20=400
When teacher also include=21*22=462
Teacher age=462-400=62
