Best Answer Explained in Below-:

Let's find the teacher's age:

Total age of students: Average age * Number of students = 10 years/student * 32 students = 320 years
New average with teacher: Old average + 1 year = 10 years + 1 year = 11 years
Total age including teacher: New average * Total (students + teacher) = 11 years/person * 33 people = 363 years
Teacher's age: Total age including teacher - Total age of students = 363 years - 320 years = 43 years

Therefore, the teacher's age is 43 Years.

So the answer is 43 Years.
