Answer 1

A=35.5               A=36
N=40                  N=41(Including class teacher) 
S=1420              S=1476
S=1476-1420=56kg is the weight of the class teacher.

Answer 2

Answer:

The weight of teacher is 56 kg.

Step-by-step explanation:

It is given that the average weight of the 40 students is 35.5 kg.

$Average=\frac{\text{Total weight}}{\text{Number of students}}$

$35.5=\frac{T_1}{40}$

$T_1=1420$

The average weight along with the class teacher is 36 kg.

$36=\frac{T_2}{41}$

$T_2=1476$

Tthe difference of total weights is

$1476-1420=56$

Therefore the weight of teacher is 56 kg.
