the average age of 40 students is 12 years.
If the teacher age is also included,the average age increases by one year.
What is the weight of teacher?
:
Not sure what his weight is but we should be able to find his age (a)
:
= 12 + 1
= 13
480 + a = 41 * 13
480 + a = 533
a = 533 - 480
a = 53 yrs is the teacher's age
