We Got Ur Question, Just Follow These Steps

________________________________

The average weight of 29 students is 40kg.

Total weight=40*29=1160

Now as the teacher joins total =29+1=30

And the average rises up by 500grams

So new total weight=30*40.5=1215

Weight of teacher = Weight of 30(teacer+students)-Weight of 29students

i.e 1215–1160=55
