total weight of student along teacher=41×36=1476kg

teacher weight=1476-1420=56kg

Answer 2

Answer:

The weight of teacher is 56 kgs

Step-by-step explanation:

Let total weight of 40 students br x

Let weight of teacher be y

Average) =total weight /total students

35.5=x/40

X=40*35.5

=1420 kgs

Now adding weight of teacher (teacher is included in 40 students)

1420kg+y

Average=1420+y/41

36=1420+y/41

36*41=1420+y

1476=1420+y

1476-1420=y

56=y

So, weight of teacher is 56 kgs
