6. 36 boys in a class weigh 42 kg on average. If their teacher is included, the
average increases by 1.5 kg. How much does the teacher weigh?​

Answer 1

Answer:

Number of students = 36

Average weight of the students = 42 kg

Total number of people in the class = 36 + 1 ( +1 The Teacher) = 37

Final Average weight of the people in the class = 42 + 1.5

= 43.5

So the initial total weight would be = 36 ×42 =1512kg

And the final total weight would be = 37×43.5= 1609.5

Therefore , the wieght of the teacher would be => 1609.5-1512=97.5
