Question

The weight of the students (in kg) in a class is given as follows:

45, 40, 35, 30, 25, 45,40, 20

What is the average weight of the class?

• A.
  40
• B.
  43
• C.
  35
• D.
  30

Answer 1

The correct option is C

35
We know,
$Average=\frac{Sumofallobservations}{Totalnumberofobservations}$

In this case, we have

$Average=\frac{45+40+35+30+25+45+40+20}{8}$

$\frac{280}{5}$ = 35

Hence, average is 35
