Question

in a class the average weight of 40 students is 35.5 kg is the average weight along with the class teacher is 36 kg what is the weight in kg of the class teacher

Answer 1

Answer:

56 Kg

Step-by-step explanation:

Number of students = 40

Average Weight of students = 35.5 kg

So, Total weight of the class = 40 × 35.5 kg = 1420 kg

Average weight when teacher is added = 36

Total weight along with teacher = 36 × (40+1) = 1476 kg

Weight of teacher,

= Total weight along with teacher - Total weight without teacher

= 1476 kg - 1420 kg

= 56 kg

∴ Weight of the teacher is 56 Kilograms
