Answer 1

Answer:

The average weight of the 12 students is 40 kg.

Step-by-step explanation:

Let the weight of the 12 students be x

The teachers weight is 66 kg

Total people = 12 students+1 teacher

We know,

Average = Sum of observations/No. of observations

42 = (66+x)/13

546 = 66+x

x = 480 kg

The weight of the 12 students is 480 kg.

Now we have to find the average weight of the 12 students.

Average = 480/12 = 40 kg

Therefore the average weight of the 12 students is 40 kg.
