Question

average age of 32 students is 10 years . if the teachers age is also included the average age increased by one year. what is the age of the teacher​

Answer 1

Answer:

43

Step-by-step explanation:

32 have average age of 10, so total age will be 320.

when teacher is added there are 33 people in total and their avg. is inc. to 11, so for this the total age will be 363.

for getting the age of teacher we will subtract 363 by 320, so by this we will get the age of the last person who is added to the total amount of the people.

Teacher age=363-320=43
