Question
Average age of a class of 28 students is 10
years. Average age of the class is increased by 12 months if the age of the teacher is included. Find the age of the teacher.Solution
Sum of the ages of all the students in the class = 28 × 10 = 280 years
Sum of the ages of the students along with teacher = 29 × 11 = 319 years
So the age of the teacher = 319 – 280 = 39 years
